Humidity/temperature probe head

0636 9730
Humidity/temperature probe head
  • 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.
    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.
     

    Humidity/temperature probe head including calibration protocol.

    Please do not use the probe head in condensing atmospheres. For continuous application in high-humidity ranges
        > 80% RH at ≤ 30 °C for > 12 h
        > 60% RH at > 30 °C for > 12 h
