M202 Precision Absolute Pressure Barometer

M202 Precision Absolute Pressure Barometer

The Meriam M202 precision absolute pressure gauge uses a portable and handheld device to obtain the accuracy of the calibration table. This pressure sensor is made entirely of 316SS and can operate in liquid, gas, and corrosive environments compatible with 316SS. The combination of precision and fluid compatibility makes M202 an ideal instrument for real-time measurement, experimentation, and environmental monitoring of absolute zero correlation pressure.

M202 features include collecting minimum and maximum values (Min/Max), tare weight readings, and user selectable engineering units. The optional altitude function allows users to input the on-site altitude to display the local atmospheric pressure or correct it to sea level atmospheric pressure. You can choose to display the user's reference altitude (reference map or triangulation) or the American Standard Atmosphere (1962) altitude. The altitude function and Min/Max, tare weight characteristics make M202 a useful tool for surveyors to accurately measure altitude changes.
