Humidity/temperature probe head

Order-Nr.  0636 9730

  • Intuitive: parallel determination of relative humidity and air temperature in indoor areas, including long-term measurement

  • Precise: measuring accuracy ±2% RH / ±0.5 °C, measuring range: 0 to 100% RH / -20 to +70 °C

  • 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 humidity/temperature probe head.
