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 even impressive where the climate is critical. This is because it enables a high level of measuring accuracy and the measurement of higher temperatures (up to +120 °C).
Uses compatible humidity sensors to calculate and display relative humidity, absolute humidity, and dewpoint
Ethernet, relay and analog outputs allow for optimum integration into individual automation systems
Self-monitoring and early warning function ensure high system availability
P2A software for parameterization, adjustment and analysis
High-quality plastic housing and optional 2-line LCD display
Additional ordering options include: analog output/supply, menu language and display, cable entry, Ethernet module, humidity/temperature units for 2 channels, and relay
Accuracy up to +/- 1.7 %RH, depending on attached probe
