The differential pressure transmitter testo 6381 was developed specially for monitoring differential pressure in the measuring range from 10 Pa to 1000 hPa. In cleanroom technology, the maintenance of positive pressure prevents the entry of contaminated air. In addition to this, the flow velocity or the volume flow can be calculated from the measurement of the differential pressure in a Pitot tube. Thanks to an optional probe from the probe series 6610, the additional recording of humidity and temperature with one instrument is also possible. The testo 6381 is particularly outstanding thanks to the automatioc zero-point adjustment which ensures high accuracy and long-term stability. The integrated self-monitoring and early warning function also guarantees the operator high system availability.
