Our Meriam brand Altimeter/Indicated Air Speed Tester is used for testing and calibration of altimeter and air speed instruments. It accurately measures pressure from 0 to 30 psi or 0 to 100 psi relative to absolute zero.

 In Pressure mode, the M2003 displays pressure in a variety of Customary and SI measurement units. Selecting the ALT or IAS switches the M2003 to Altitude mode for us in checking altimeter instrumentation. Customary or SI measurement units for Altitude and Indicated Air Speed are selectable by the customer.

 A time leak test function is standard for Pressure mode. Customers set the test period and the test. The M2003 displays Minimum, Maximum, and Live Measurements. The leak rate per minute upon completion.



Meriam’s M2000 Digital Calibrator is a portable pressure instrument that offers flexible features to help meet the demand of your everyday pressure measurement needs. The M2000 features NIST traceable accuracy ± 0.02% FS + 0.005% Reading standard on each device. Pressure sensors both non-isolated and isolated (316SS) measure absolute, differential, compound.

A significant benefit of the M2000 is its ability to measure a second pressure range with the addition of a Meriam Tethered Sensor (MTS). Choose from any available pressure sensor type and range and connect your accessory MTS via a locking tether cable. See our attached data sheet for available pressure ranges.

With an easy to use and intuitive interface, the M2000 offers fast and simple operation. Mobile data logging allows for computer-free use when measuring out in the field.

Add Data Log Pro to expand on the M2000 data logging capabilities. Data Log Pro adds the ability to store up to 128 log files or 100,000 data points while also giving you the ability to modify data log options and settings.



Meriam’s M1000 Digital Calibrator is a single function, portable pressure instrument with flexible features to meet many of your everyday pressure measurement needs. The device features an easy and intuitive user interface with convenient pressure connections.


  • Damping to stabilize fluctuating pressure signals
  • Zero key and user adjustments for manual calibration
  • Protective Red Boot
  • Compound, Absolute and Differential pressure sensors
  • Wide variety of ranges available: -14.5 psi to 100 psi
  • Optional pressure fitting, vacuum, and hand pump kit
  • O­ffering the following measurement units: mmHg, inHg, inH2O, mmH2O, kPa, mbar, and psi



Meriam M2001 makes drop testing Rotary (Natural) Gas Meters easy. Hardware options protect the M2001 from one sided overpressure. The unit comes with either a brass push-to-read valve or stainless 3 valve manifold.

  • Displays live DP reading and at the end of the test it will display a true average of the DP.
  • Unit will give you the total time elapsed and you can toggle between the minimum and maximum pressures.
  • 316SS media isolated pressure sensors to suit a wide range of applications
  • Features damping to stabilize fluctuating pressure signals.
  • This device ships with calibration certificate traceable to NIST
  • Intrinsically Safe options available




The meriGauge® plus is a break-through digital pressure gauge with modular sensors. This new gauge is Meriam’s latest offering in the pressure measurement line. The meriGauge® plus is unique in that it features the capability to support detachable sensors to meet all of your range requirements.

This modular system allows you to purchase only the pressure ranges you need, for less than the cost of a stand-alone pressure gauge.  To add to the efficiency of this gauge, the small sensors contain the calibration and they are easily exchanged for calibration so the gauge itself is never “out for calibration.”

The meriSense sensors have been specifically designed to compliment this product and will be compatible with all of Meriam’s future measurement and calibration equipment.  They are available in  various types and ranges. The sensor label indicates the type of range. The meriSense sensors support 32 pressure units.



The HPT100 is a second generation pipeline integrity testing tool that provides real time measurements and data logging during a hydrostatic or pneumatic pipeline test. The HTP100 reduces costs, set up time, and uses advance technology delivering ultimate, real-time reporting capabilities including data logging, exportable test logs, user configurable inputs and multiple engineering units making the HPT100 an essential tool for any pipeline tester. Powered by readily available 12VDC the HPT100 and a battery backup will record hours of uninterrupted test results.

Easy to use, the HPT100 comes with everything pipeline testers need to record pressure, temperature, and other test data.  There are multiple measurement solutions all in one device, easily accessible to increase efficiency during pipeline test sections making the Hydro/Pneumatic tester an essential tool for pipeline testers.

Features on Hydro/Pneumatic Tester

  • Specialized tool for hydrostatic & pneumatic integrity testing
  • One device with correlated independent measurements
  • Three (3) operation modes: Live, Record, and Review
    • All data logs are date time stamped
    • PDF or Excel (txt. file) report generation
    • Hide/show measurements on graph
  • Time stamped notes entry
  • User selectable measurement units




The AA100 is a first of its kind diagnostic tool that provides real-time measurements from an autoclave during a sterilization cycle. The Autoclave Analyzer allows technicians to connect up to 4 RTD temperature probes and 2 pressures hoses to the steam sterilizer system, and capture all the measurements as they are happening during the autoclave run cycle. This provides real-time data and a clear picture of these critical measurements as the system is processing. 

The AA100 measurement data is highly accurate, NIST traceable, and time-synchronized. With data logging, the AA100 records the current test cycle as well as maintains data from the previous test cycles. 

Technicians can monitor a steam sterilization cycle in real-time. With this data, they can quickly identify and repair equipment that does not perform according to their specifications.  Reducing diagnosis and service time leads to move service calls per day. Ultimately, improving efficiency while adding to customer satisfaction.
