- High-precision Testo humidity sensors with long-term stability (± 1.7% RH) can be ordered for the transmitter
- Ethernet, relay and analogue outputs allow optimal integration into individual automation systems
- High-quality digital probes (to be ordered) and intelligent calibration concept
- Self-monitoring and early warning function ensure high system availability
In combination with the testo 660x probe series, the testo 6651 temperature and humidity transmitter meets high demands in air conditioning technology. Testo's temperature/humidity transmitter is impressive even where the climate is critical. This is because it enables high measurement accuracy and the measurement of higher temperatures (up to +120°C).
