    Humidity/temperature probe head

    0636 9730
  1. Intuitive: parallel determination of relative humidity and air temperature in indoor areas, including long-term measurement
  2. Precise: measuring accuracy ±2% RH / ±0.5 °C, measuring range: 0 to 100% RH / -20 to +70 °C
  3. Convenient: probe head is easy to attach to the universal handle with Bluetooth® or cable (available to order separately)
  4. Intelligent calibration concept: only send in the probe head for calibration
    5. 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.
    Proven quality from Testo: you can depend on reliable measurement results, because the probe head is equipped with our long-term stable humidity sensor. This is traceable to international humidity standards, such as ILAC, PTB and NIST.
