Pressure meters for all measurement ranges. Highly accurate with internal differential pressure sensor, ideal for inspecting extraction units and ventilators and for monitoring pre ssure 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. Features: Calibration protocol Multi point and timed mean calculation 2 probe sockets for pressure and temperature Calculation of velocity and volume flow via Pitot tube measurement Save data according to site and analyze on PC or notebook computer Temperature compensated differential pressure sensor 0 to 100 hPa integrated in instrument Long term analysis with internal data memory Accuracy 0.1 percent of fsv Battery Show more
