Testo 6381 Differential pressure transmitter in cleanroom-conform panel design. The Testo 6383 was developed specially for monitoring low differential pressures in the measuring range from -10 to 10 Pa. In cleanroom technology, the maintenance of positive pressure prevents the entry of contaminated air in critical zones. Thanks to an optional internal or external 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 automatic 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. Areas of application: monitoring positive and negative pressure in cleanrooms, operating theatres and isolation rooms, optional monitoring of humidity and temperature in cleanrooms. Ethernet, relay and analog outputs allow optimum integration into individual automation systems. Self-monitoring of the transmitter and early warning function guarantee high system availability. Configurable alarm management with adjustable response delay and alarm acknowledgement.
