Testo 6381 differential pressure transmitter with flow calculation

The testo 6381 transmitter is specially designed for monitoring differential pressure in the measuring range from 10 Pa to 1,000 hPa. In cleanroom technology, maintaining positive pressure prevents the ingress of contaminated air. To keep cleanroom conditions constant, the transmitter also calculates volume flow and flow rate from the measured differential pressure. An optional probe from the testo 6610 probe series also allows simultaneous recording of humidity and temperature with one transmitter. A particularly notable feature of the testo 6381 differential pressure transmitter is its automatic zeroing, which ensures high accuracy and long-term stability. The integrated self-monitoring and early warning function also guarantee high system availability for the operator.
