Hot wire probe head including temperature and humidity sensor
0635 1570Hot wire probe head including temperature and humidity sensor
0635 1570Intuitive: parallel determination of relative humidity and air temperature in indoor areas, including long-term measurement
Precise: includes absolute pressure compensation, calculation of wet bulb temperature, dew point and absolute humidity
Convenient: simply plug the probe head onto the extendable telescope for air velocity probes – and use the adapter to attach them 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 hot wire probe head.
