Differential pressure meter 0 to 100 hPa incl. battery and calibration protocol.

Highly accurate with internal differential pressure sensor, ideal for inspecting extraction units and ventilators and for monitoring pressure drops in filters. When used with the Pitot tube, the internal pressure sensor measures velocities from 5 - 100 m/s. The 100 Pa probe, which can be connected externally, measures accurately from 1 - 12 m/s.
