Meriam M200LS Lab Standard Smart Manometer

Meriam M200LS Lab Standard Smart Manometer/Pressure Calibrator

     The Meriam M200LS Lab Standard Smart Manometer offers the best available pressure measurement accuracy in a portable, handheld format. The NIST traceable accuracy is typically ±0.01% of F.S. and is independent of temperature effect over an operating temperature range of 59º to 86º F. Pressure ranges from 28” H2O F.S. to 500 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.

Meriam M200LS Features:

Accuracy
Accuracy: + 0.01% FS
(+ 0.02% F.S. for DN0028) No temperature effect from 59° to 86° F (15° to 30° C).
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. See Meriam’s M200-DI for wet/wet DP requirements.
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.
Auto Shut-Off
User selectable shut-off. Programmable for Disable, 10, 20, 30, 45, 60 minutes.
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.
Auto Record
Document up to 240 readings (automatically or manually) to reduce paperwork and field time. Saved readings can be recalled at any time.
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.
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. Enables users with accurate primary standards to calibrate their devices locally if desired.
