ManoAir500 Micromanometer (Low-Pressure manometer)

The versatile differential pressure micromanometer ManoAir500 displays Pa, mbar and mmH2O for pressure as well as the air-flow velocity of gaseous media.

Thereby media temperature, effective ambient pressure and humidity are considered.

Technical data

Digital-micro-manometer

In addition to its universal usage as a relative and differential micro-manometer the ManoAir500 can also be used as a volume flow meter, if pipe or channel dimensions are known. Medium temperature and barometric pressure are automatically compensated
