Pressure calibration work often requires a stable, controllable pressure source.

In many field and shop environments, technicians use hand pumps to generate pressure for testing or calibrating pressure gauges, pressure transmitters, pressure switches, flow computers and related instrumentation. For low and moderate pressures, a standard pneumatic hand pump may be enough. For higher pressures, many teams move to hydraulic pumps or bottled nitrogen.

The Martel MECP2000 fills a useful gap. It is a portable high-pressure pneumatic hand pump designed to generate up to 2000 psi / 140 bar by hand, while also supporting vacuum down to -14 psi / -0.9 bar. The original JM Test article positions it as an alternative to hydraulic pumps or heavy nitrogen cylinders for certain high-pressure calibration jobs.

For Canadian instrumentation technicians, calibration labs, oil and gas sites, utilities, water and wastewater facilities, food-processing plants, mines, refineries and field-service teams, the MECP2000 can be useful when the job needs high pneumatic pressure without the mess, contamination risk or handling burden of hydraulic fluid or nitrogen cylinders.

What Is the Martel MECP2000?

The Martel MECP2000 is a portable high-pressure pneumatic test pump.

It is used to generate air pressure or vacuum for pressure calibration and testing work. When paired with a calibrated pressure gauge, pressure calibrator or reference indicator, it can function as a portable pressure source for comparing and adjusting pressure instruments.

The MECP2000 is not the reference standard by itself. It generates the pressure. The calibrated gauge or pressure calibrator connected to it provides the measurement reference.

The Martel datasheet lists the pressure range as -14 psi / -0.9 bar to 2000 psi / 140 bar, with two ¼ inch FNPT pressure connections and two BSP adapters included. The datasheet also lists the size as 21.5 in × 10.6 in × 4.5 in / 55 cm × 27 cm × 11.5 cm and the weight as 15 lb / 6.8 kg.

Key Specifications

The source article and datasheet both highlight the MECP2000’s dual-stage pump design, precision vernier, vent valve, double output manifold, rugged construction and isolation valve for better fine control.

How the Dual-Stage Pump Design Helps

The MECP2000 uses a dual-stage pump design.

The first stage is a low-pressure, high-volume chamber. This stage helps pre-charge a secondary high-pressure chamber. The second stage then brings the system up to higher pressure with less effort than a simple single-stage hand pump would require.

This matters because generating high pneumatic pressure by hand can be difficult.

At lower pressure, volume movement matters. At higher pressure, force and control matter. The dual-stage design helps the pump build pressure more efficiently while keeping the pump motion smooth through the stroke.

For field technicians, this can reduce operator fatigue and make high-pressure pneumatic calibration more practical.

Why Pneumatic Instead of Hydraulic?

Hydraulic pumps are commonly used for high-pressure calibration because liquids are easier to pressurize than gases.

However, pneumatic calibration has advantages in some applications.

A pneumatic hand pump may be preferred when:

• The instrument is designed for gas service
• The process cannot tolerate hydraulic fluid contamination
• The technician wants to avoid oil or water in the test setup
• The job is in a clean environment
• The instrument must be tested with air or inert gas
• The user wants a lighter alternative to some hydraulic setups
• Nitrogen cylinders are not convenient
• The pump is being used as a backup pressure source

The source article specifically lists high-pressure calibration where hydraulic pumps are not preferable and eliminating the need for nitrogen cylinders, or using the pump as backup to nitrogen, as MECP2000 applications.

For Canadian process and instrumentation work, this is especially useful where contamination control, field portability or cylinder logistics matter.

What the Precision Vernier Does

The vernier control is one of the most useful features on the MECP2000.

A vernier lets the technician fine-tune pressure after the pump has generated the approximate pressure level. This is important because pressure calibration requires stable, controlled setpoints.

The source JM Test article states that the precision vernier allows pressure to be fine-tuned with high resolution at both high and low pressures. It also notes that the vernier chamber provides enough range to generate low pressures around 200 inH₂O / 500 mbar without pumping.

This means the MECP2000 can support both:

• High-pressure pneumatic calibration up to 2000 psi
• Lower-pressure calibration work where fine control is more important than pumping force

That makes it more versatile than a pump that is only comfortable at one end of the pressure range.

Common Applications

Pressure Gauge Calibration

The MECP2000 can be used as a pressure source when checking a pressure gauge against a calibrated reference gauge or digital pressure calibrator.

A typical setup includes:

• MECP2000 pump
• Calibrated reference gauge or pressure calibrator
• Gauge under test
• Correct hoses and fittings
• Leak-free connections
• Pressure setpoints
• As-found and as-left readings where required

The Martel datasheet shows the MECP2000 paired with a BetaGauge PI-PRO as a gauge comparator setup.

Pressure Transmitter Calibration

Pressure transmitters need a known pressure input and a measured electrical output.

In a typical transmitter calibration, the pump generates pressure while a pressure calibrator or reference gauge confirms the applied pressure. The technician then compares the transmitter’s output against the expected value.

The MECP2000 may be useful when the transmitter range is too high for ordinary pneumatic pumps but the technician still wants to avoid hydraulic fluid.

Pressure Switch Testing

Pressure switches often need to be checked at their trip and reset points.

A stable pressure source and fine adjustment are important because the technician may need to approach the setpoint slowly and record exactly where the switch changes state.

The MECP2000’s vernier control can help with controlled pressure changes near the switch point.

Flow Computer Calibration

The source article lists flow computer calibration for custody-transfer applications as an MECP2000 application.

For Canadian oil and gas or process applications, this claim should be used carefully. Custody-transfer work may have strict measurement, procedure, documentation and regulatory requirements. The pump can provide pressure generation, but the complete calibration system must include the correct reference standards, procedure, uncertainty and documentation.

Bench-Top Gauge Comparator

The MECP2000 can be used on a bench as a gauge comparator.

This is useful when a shop needs to compare pressure instruments without setting up larger calibration equipment.

The datasheet specifically lists bench-top gauge comparator as an application.

General Pneumatic Calibration

The pump can also support general pneumatic calibration work for gauges, transmitters, switches and other pressure devices within its range and media compatibility limits.

MECP2000 Features Explained

High Pressure by Hand

The MECP2000 can generate up to 2000 psi / 140 bar by hand. That is the main product advantage compared with many lower-pressure pneumatic hand pumps.

Vacuum Capability

The pump can also generate vacuum down to -14 psi / -0.9 bar. This lets the technician support both pressure and vacuum checks with one tool where the application allows it.

Dual Output Manifold

The pump has a double output manifold with ¼ inch female NPT fittings and includes BSP adapters.

This helps connect both the reference instrument and the device under test.

Vent Valve

The vent valve provides controlled pressure release.

The source article notes that the vent valve vents at the pressure connection to help prevent pump contaminants from entering the test system.

Isolation Valve

The isolation valve helps protect the pump and increases the fine-control range.

In practice, this is useful when the technician wants to isolate the generated pressure and make smaller adjustments with the vernier.

Portable or Bench-Top Use

The MECP2000 can be used as a portable field pump or as a bench-top comparator.

This gives calibration teams flexibility between shop work and field service.

What the MECP2000 Is Not

The MECP2000 is a pressure generation tool. It should not be described as a complete calibration standard by itself.

It does not replace:

• A calibrated pressure gauge
• A digital pressure calibrator
• A deadweight tester
• A documented calibration procedure
• A pressure reference with suitable uncertainty
• A leak test procedure
• A safe pressure-test setup
• A certificate for the device under test

For calibration work, the pump must be paired with a suitable reference instrument. The reference instrument’s calibration, uncertainty and traceability are what support the measurement result.

Pressure Calibration and Traceability in Canada

For Canadian calibration copy, use traceability language carefully.

A good Canadian statement is:

Pressure calibration should be supported by documented metrological traceability to SI units through NRC Canada, NIST or another recognized national metrology institute, with measurement uncertainty suitable for the intended application.

NRC Canada’s Metrology Research Centre is Canada’s national metrology institute and is responsible for developing and disseminating accurate measurement standards. NRC also describes contractual traceability expectations as requiring valid, current documentation and records supporting the calibration process.

For accredited calibration claims, do not assume every pressure range, instrument type or service location is covered. In Canada, SCC is responsible for accreditation to ISO/IEC 17025 for testing and calibration laboratories.

For the Canadian article, avoid saying:

“Every MECP2000 calibration setup is ISO/IEC 17025 accredited.”

Use:

“Confirm the required certificate type, accredited scope, measurement uncertainty and traceability before booking calibration or rental equipment.”

Safety Considerations for High-Pressure Pneumatic Testing

High-pressure pneumatic testing deserves respect.

Compressed gas stores energy. A failed fitting, damaged hose, loose adapter or overpressurized instrument can create a sudden release of energy.

Canadian teams should consider:

• Manufacturer pressure ratings
• Rated hoses and fittings
• Correct thread type
• Clean, dry test media
• Proper adapters
• Eye and hand protection
• Secure test setup
• Controlled pressure release
• No overpressure
• No damaged hoses
• No improvised fittings
• No standing directly in line with pressurized connections
• Depressurizing before disconnecting

CCOHS recommends not exceeding the manufacturer’s specified pressure rating for pneumatic tools, hoses or fittings, and recommends turning off air pressure when hoses are not in use or when changing tools. It also recommends using a safety cable or whip check to prevent uncontrolled hose movement if a coupling fails.

For the Canadian page, add a clear note:

Do not exceed the lowest-rated component in the pressure setup. The pump may be capable of 2000 psi, but the gauge, hose, adapter, fitting or device under test may have a lower pressure rating.

Fittings: NPT, BSP and Canadian Field Reality

The MECP2000 uses ¼ inch FNPT pressure connections and includes BSP adapters.

That is useful because Canadian facilities often contain both North American and imported instrumentation.

However, fittings should not be mixed casually. NPT, BSPP and BSPT threads can look similar but use different thread forms and sealing methods. Using the wrong adapter can cause leaks, damaged threads, unsafe connections or inaccurate readings.

For this article, use simple, safe guidance:

• Identify the instrument thread before connecting.
• Use the correct adapter.
• Use the correct seal method.
• Do not force threads together.
• Confirm pressure rating of every adapter and hose.
• Leak-check the setup before raising pressure.
• Depressurize before changing connections.

When the MECP2000 Makes Sense

The MECP2000 is a strong option when:

• Pneumatic pressure is preferred over hydraulic fluid
• Nitrogen cylinders are inconvenient
• The job needs pressure above common pneumatic hand pump ranges
• The technician needs both pressure and vacuum capability
• Fine pressure adjustment is required
• The setup needs two pressure ports
• The pump will be used in the field and on the bench
• Gauge comparison work is common
• High-pressure transmitter or switch testing is required

It may be especially useful for:

• Instrument technicians
• Calibration labs
• Field-service crews
• Oil and gas measurement teams
• Utilities
• Water and wastewater teams
• Food and beverage facilities
• Mining sites
• Chemical plants
• Refineries
• Manufacturing plants

When a Different Pump May Be Better

The MECP2000 is not the right tool for every job.

A lower-pressure pneumatic hand pump may be better when:

• The range is below 100 psi or 125 psi
• The work is mainly HVAC or low-pressure differential testing
• The technician needs a lighter handheld pump
• The device under test is sensitive to small pressure changes
• The setup does not require high-pressure capability

A hydraulic pump may be better when:

• The pressure is above 2000 psi
• The application requires liquid media
• The pressure range is better suited to hydraulic generation
• The device under test is liquid-filled
• The procedure calls for hydraulic pressure

A deadweight tester or pressure controller may be better when:

• The work requires very low uncertainty
• Lab-grade calibration is needed
• Automated calibration is required
• Repeatability and reference performance are more important than field portability

The correct pressure source depends on the pressure range, media, accuracy requirement, safety requirement and calibration procedure.

Practical Setup Tips

Before using the MECP2000, confirm:

• The required pressure range
• Whether pneumatic media is suitable
• The maximum pressure rating of the device under test
• The maximum pressure rating of the reference gauge
• Hose and fitting pressure ratings
• Thread type and adapter requirements
• Whether BSP adapters are needed
• Whether the test setup is leak-free
• Whether the reference gauge is calibrated
• Whether the test points are defined
• Whether a certificate is required
• Whether the work is field or bench-top
• Whether the setup needs pressure and vacuum
• Whether the work area is safe for pneumatic pressure testing

During use:

• Increase pressure slowly.
• Approach each test point carefully.
• Use the vernier for fine adjustment.
• Allow pressure to stabilize before recording readings.
• Avoid overpressuring the device under test.
• Vent pressure in a controlled way.
• Depressurize before disconnecting fittings.
• Record as-found and as-left readings where required.

Common Mistakes to Avoid

Treating the Pump as the Reference

The MECP2000 generates pressure. It does not provide the measurement reference unless it is paired with a calibrated pressure instrument.

Ignoring the Lowest-Rated Component

The safe working pressure of the setup is limited by the lowest-rated component, not the pump’s maximum pressure.

Using the Wrong Thread Adapter

NPT and BSP threads are not automatically interchangeable.

Overusing Sealant

Too much sealant can contaminate fittings, gauges or the device under test.

Not Leak-Checking the Setup

A small leak can make readings drift and waste time during calibration.

Using Hydraulic Equipment Logic for Pneumatic Testing

Gas is compressible. Pneumatic pressure testing can store significant energy and should be controlled carefully.

Assuming Canadian Rental Availability

The US source page links to rent and purchase options for the MECP2000. For the Canadian page, do not make a firm claim unless JM Test Systems Canada confirms that the exact model, kit, accessories and rental terms are available locally.
