PRESSURE CALIBRATORS AND DIGITAL MANOMETERS
Meriam Merical Manometer / Pressure
Calibrator
The Meriam Meri-cal pressure calibrator display simultaneously indicates pressure (or differential pressure) and electronic transducer/transmitter output in any of eight key selectable engineering units. The Meriam Meri Cal continues to provide the most cost effective and useful method of precise measurements.
The Meri-Cal may be used for test measurement of pressure or differential pressure and as a calibrator for mechanical recorders, gauges, pneumatic controls and electronic transducers and transmitters.
Meriam M200 Smart Manometer/Digital Manometers
Meriam's M2 Series Smart Manometers bring high precision and value to handheld, digital manometer users. The M2 features NIST traceable accuracy of + 0.025% of F.S., independent of temperature effect, at the lowest prices available. Pressure ranges from 10" H2O F.S. to 3000 PSIG F.S. are available. M2 pressure sensors are available to measure gauge, compound, differential, absolute or vacuum pressure.
The display can read out in any of eleven pressure units or can be linearly scaled for special user units. Differential models offer a square root flow function to display flow rate in user defined units. An adjustable damping feature minimizes the effects of pulsating pressures. A Min/Max function captures the extremes of pulsating or varying pressure signals and a Hold function can freeze the display at any point of interest. Auto Record documents up to 240 readings for future recall.

Typical applications include temperature calibration, temperature verification and temperature measurement.
Meriam M334 Loop Calibrator
The Meriam M334 is a state of the art, highly reliable, rugged and easy to use milliamp calibrator. It has the functions necessary to perform all the required maintenance and calibration tasks of virtually any 4-20mA loop. It provides source and read milliamp functions along with power and measure and two wire transmitter simulations. In addition it can measure DC Voltage for troubleshooting power supplies.
The M334 is functionally equivalent to similar calibrators with many additional benefits. These improvements include better long term stability, accuracy, reliability and ruggedness including significantly improved battery life. The combined improvements allow the Meriam M334 to meet or exceed all of the expected performance and functions of similar products.
Meriam M203 Altimeter
The M203 Altimeter / Indicated Air Speed Tester accurately measures pressure from 0 – 900 mm Hg (17.40 PSI) relative to absolute zero. Selecting the "ALT / IAS" unit from Program Mode converts the M203 to Altitude Mode for use in checking altimeter instrumentation. Pressing the ALT / IAS button toggles the M203 to Indicated Air Speed Mode for checking air speed instrumentation. Pressing the ALT / IAS button again returns to the Altitude display. English or S.I. units for Altitude and Indicated Air Speed are user selectable.
A timed leak test function is standard for Pressure, Altitude and Indicated Air Speed modes. The user sets the test period and starts the tests. The M203 displays Minimum, Maximum and instant values during the test period and then the leak rate per minute upon completion. Other features include Minimum / Maximum value capture, selectable damp rate, back light, programmable auto-off timer and record function. Four "AA" alkaline batteries provide more than 100 hours of continuous use.
Meriam M202 Precision Absolute Manometer
Meriam's model M202 Precision Absolute Manometer brings calibration bench accuracy to a portable, handheld unit. This combination of accuracy and fluid compatibility makes the M202 ideal for environmental, test or real-time process measurements of pressure relative to absolute zero. General Purpose (G.P.) and Intrinsically Safe (I.S.) models are available.
The M202 includes features for minimum and maximum (Min/Max) value capture, tare readings and user selectable engineering units. A selectable altitude function allows users to enter site altitude above sea level in order to display local barometric pressure or barometric pressure corrected to sea level. User referenced altitude (referenced to map or trig markers) or altitude based on US Standard Atmosphere of 1962 can be selected for display. Using the altitude function with the Min/Max and Tare features makes the M202 very useful as a surveyor's tool to accurately measure changes in altitude.
M201 Rotary Gas Meter Tester
It has been proven for several years now that the differential testing of rotary meters can be an effective supplementary or even primary field proving method. These tests can in some instances be completed in just a few minutes and can save a utility thousands of dollars. Using this proven testing method and test equipment on a more frequent basis than transfer proving can and will prove beneficial to any utility, large or small.
Meriam's M201 has new features to make drop testing Rotary (Natural) Gas Meters even easier! New hardware options protect the M201from one sided overpressure. Options include a 1/4 turn valve manifold and an integral push-to-read cartridge valve in addition to the traditional push-to-read valve manifold. More importantly, new operating features provide users with a live pressure display and more automation to make field use easier than ever before.
