Differential pressure transmitters with high accuracy and long-term stability

Differential pressure transmitter with humidity/temperature option

testo 6651 humidity/temperature transmitter for critical climate, accuracy up to ±1.7 %RH (depends on the probe), selectable signal outputs, optional display, optional ethernet module, optional relay, 2 analog outputs

The testo 6681 temperature and humidity transmitter is designed for monitoring critical climate in industrial processes (e.g. production/process engineering). If these involve maximum precision or specialized applications (high humidity, trace humidity, etc.), then this climate transmitter is the ideal choice because, when it comes to humidity measurement, it features unrivalled cutting-edge technology.

The Ethernet connector can be easily patched to an existing network cable. The special connector ensures tightness according to IP protection class IP65.
