Meriam's model 355 Precision Absolute Manometer puts calibration bench accuracy in a portable, handheld unit. The pressure sensor is all 316ss allowing it to be used with liquids, gases and corrosives compatible with 316ss. This combination of accuracy and fluid compatibility makes the 355 ideal for test or process applications. The model 355 has a programmable altitude function that allows the user to enter the site altitude above sea level in feet or meters. This allows the user to chose between displaying local barometric pressure or pressure corrected to sea level. User set altitude or altitude based on U.S. Standard Atmosphere of 1962 can be displayed. The altitude function used with the Min/Max and Tare makes the model 355 useful as a surveyor's tool by accurately measuring changes in altitude. FEATURES/SPECIFICATIONS:
