M202 Absolute Manometer
Precision absolute manometer brings calibration bench accuracy to a portable, handheld unit
Meriam’s model M202 Precision Absolute Manometer brings calibration bench accuracy to a portable, handheld unit. The pressure sensor is all 316 stainless steel, allowing it to be used with liquids, gases, and corrosives that are compatible with 316 stainless steel. 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.
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.
This product is an updated version of the 355.
