DT-3890/3890A/3890B

Differential/Absolute Pressure Manometers
DT-3890A is an absolute pressure measuring instrument. It is normally used to measure absolute pressure, e.g. for pressure compensation in velocity measurement in ducts, laboratories and production processes. Further measurement parameters are barometric (surface) pressure (= pressure at sea level) and altitude above sea level.
DT-3890/3890B are Differental Pressure Manometers with large LCD display.
