High-precision humidity/temperature probe head

More applications, less equipment: if you already own one of our probes with a universal handle, you can easily expand your portfolio of probes with the high-precision humidity/temperature probe head.

Intuitive: parallel determination of relative humidity and air temperature in indoor areas, including long-term measurement
Precise: carry out humidity measurements with an accuracy of ± (0.6% RH + 0.7 % of m.v.) in the range between 0 and 90% RH, calculation of wet bulb temperature, dew point and absolute humidity
Convenient: probe head is easy to attach to the universal handle with Bluetooth^® or cable (available to order separately)
Intelligent calibration concept: only send in the probe head for calibration

Proven quality from Testo: you can depend on reliable measurement results, because the probe head is equipped with our high-precision, long-term stable humidity sensor. This measures the humidity with an accuracy of ± (0.6% RH + 0.7% of m.v.) in the range between 0 and 90% RH and is traceable to international humidity standards, such as ILAC, PTB and NIST.
