Humidity transmitter for critical climate applications

• High-precision Testo humidity sensors with long-term stability (±1.7 % RH) can be ordered for the transmitter.
• Ethernet, relay and analog outputs enable optimum integration into individual automation systems.
• High-quality digital probes (can be ordered) and an intelligent calibration concept.
• Self-monitoring and an early warning function ensure high system availability.

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
