High-precision humidity/temperature probe head
0636 9770High-precision humidity/temperature probe head
0636 9770Intuitive: 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
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.
