M200LS Lab Standard Smart Manometer
Accuracy & Resolution Table for all Engineering Unit Choices
Meriam’s 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.
Requirement:
Today’s maintenance technicians need accurate and flexible test gear to tackle as many applications as possible. Because pressure measurements made by OEM equipment can be displayed in many different engineering units, technicians need the flexibility to quickly change units and to be confident of resulting accuracy and resolution.
Solution:
Meriam’s M200LS Lab Standard Smart Manometer meets this requirement. The user selects from 11 pressure units, 1 userdefined unit or square root flow options. This handheld unit is available in differential pressure ranges from 28” to 2000” H2O (clean, dry, non-corrosive gases only), 15 to 500 PSIG and 17.4 to 38.7 PSIA to suit many measurement needs.
Standard accuracy is ± 0.01% FS (28” wc range is ± 0.02% FS) including all affects of linearity, repeatability, hysteresis and temperature from 59º to 86º F (15º to 30º C). See the table below for accuracy and resolution of each pressure unit.
Other important features:
Backlit display, 100+ hours of battery life, 1/8” NPT(F) HI and LO pressure connections.
