The air conditioning humidity transmitter

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 wall and duct bracket is the ideal solution for securely mounting the testo 66xx humidity probes. Use the bracket for either wall or duct mounting of the probe.
