Available to an accuracy level
+/-0.02% of Full Scale     

     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.
