Meriam’s M200LS Lab Standard Smart Manometer offers the best available pressure measurement accuracy in a portable, handheld format.  Why LS?  The M200LS features 60% better accuracy than our M200, and no temperature effects from 30°C - 50°C (59°C - 86°C). The NIST traceable accuracy is typically ± 0.01% of F.S. within the temperature range of 15°C - 30°C and ± 0.025% F.S. between -20°C - 15°C and 30°C - 50°C. Pressure ranges from 28 in 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. 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.

All models include a protective platinum boot, four (4) AA batteries, and a hard copy user's manual.

Note: M200LS model DN0028 (0 - 28.000 in H2O, Differential) has ± 0.02% FS accuracy.
