Meriam M2 Series Smart Manometers (M200)

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 28" H2O F.S. to 2000 PSIG F.S. are available. M2 pressure sensors are available to measure gauge, 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.

    Engineering Units

    Inches of H2O (select 4 C, 20 C, or 60 F), PSI, mm of Hg, inches of Hg, mBars, Bars, kPa, kg/cm2, cm of H2O and user selectable scaling.

    Media Compatibility

    DN: Non-isolated differential sensor for clean, dry, non-corrosive gases. GI & AI: Isolated Gauge or Absolute sensor for fluids compatible with 316L SS.

    Pressure Limits

    Twice range on Gauge and Absolute (GI and AI) units. Twice range on Differential (DN) units when pressurized on high side only and 150 PSI (10.5 Kg/cm2) static when applied to both sides of the sensor simultaneously.

    Leak Test

    Allows users to view Min/Max pressure values and calculates leak rate per minute in pressure units. The feature is very handy when troubleshooting or pressure testing pneumatic systems.

    Damping Rates

    Exponential damping with user selectable time constant from 0.1 to 25 seconds.

    Min/Max Capture

    Capture speed is equal to the selected damping rate.

    Auto Record

    Document up to 240 readings (automatically or manually) to reduce paperwork and field time. Saved readings can be recalled at any time.

    Field Re-cal

    The M2 series can be recalibrated in the field for zero, span, and linearity. The user has the option to select a 1 point or 5 point calibration procedure. This feature enables users with accurate primary standards to calibrate their devices locally if desired.

    Auto Shut-Off

    User selectable shut-off time period. Programmable at 10, 20, 30, 45, 60 minutes.

    Base Unit

    14 ounce (6.5" X 3.6" X 2.25") polycarbonate, permanently dissipative, ESD protection.


    Sealed membrane type with 5 dome contact style buttons.


    5 significant digit LCD (0.25" high) 2 line x 16 alphanumeric characters with contrast adjustment. Two stage backlight with visual overrange indication.


    4 each AA batteries providing over 100 hours of continuous use.
