Humidity/temperature probe (digital) - with Bluetooth®

0636 9731
SAR 980
  • Intuitive: clearly structured measurement menu for long-term measurement and parallel determination of the relative humidity and air temperature in indoor areas
  • Precise: calculation of wet bulb temperature, dew point and absolute humidity
  • Convenient: Bluetooth connection between measuring instrument and probe, a universal handle can easily be combined with other probe heads
  • Intelligent calibration concept
  • For measurements in storage, refrigeration and work rooms, in ventilation ducts and also on refrigeration systems and heat pumps: use the humidity/temperature probe (with the compatible measuring instrument) to measure relative humidity and air temperature. The readings are transmitted directly to your measuring instrument via Bluetooth, making your measurements particularly convenient.
    Use the humidity/temperature probe with the compatible testo multifunction measuring instrument (please order separately) to measure relative humidity and air temperature. Dew point, wet bulb temperature, absolute humidity as well as the heating and cooling output are calculated at the same time.

     

    Humidity/temperature probe with Bluetooth – features

    The readings of the humidity/temperature probe are transmitted to your measuring instrument via Bluetooth, up to a distance of 20 m.

    Particularly useful: store individual readings directly in the measuring instrument by pressing the button on the humidity/temperature probe. The clearly structured measurement menu for long-term measurement enables the measuring instrument to be operated intuitively. Reading trends are reliably recorded thanks to the convenient input of measurement time and measuring cycle. These trends enable you to evaluate changes in the data.

    Proven quality from Testo: you can depend on reliable measurement results, because the humidity/temperature probe is equipped with our long-term stable humidity sensor. This is traceable to international humidity standards, such as ILAC, PTB and NIST.

     

    Wireless and space-saving: more applications, less equipment

    Endlessly versatile: a universal handle can be connected to all probe heads – so you can master more applications using less equipment and save space. The Bluetooth handle makes it more convenient to carry out your measurement and guarantees less cable clutter in the case.

    Or order the cable handle to connect testo probe heads. This is an advantage if Bluetooth signals are not permitted. If the humidity sensor needs to be replaced in the distant future, you can change the probe head.

     

    Intelligent calibration concept

    You will get exceptionally accurate measurement results with the digital probe, because the measuring instrument makes measurement uncertainty a thing of the past. You only need to send the probe head in for calibration – so the measuring instrument remains in continuous use.

     

    Areas of application for the humidity/temperature probe

    Storage and refrigerated rooms: Thanks to a large measuring range of 0 to 100% RH and -20 to +70 °C, you can measure relative humidity and air temperature in storage and refrigerated rooms with reliability.

    Work rooms: If the air is too dry or too humid, this affects our well-being and the comfort level. Use the humidity/temperature probe to monitor relative humidity, air temperature, dew point and wet bulb temperature in work rooms. For long-term measurements, measurement data trends can be recorded in the compatible measuring instrument.

    Ventilation ducts: With a probe head diameter of 12 mm, the probe is ideal for humidity and air temperature measurements in ventilation ducts. Dew point, wet bulb temperature and absolute humidity are automatically calculated in the compatible measuring instrument.

    Refrigeration systems and heat pumps: Heating and cooling output are important parameters for adjusting refrigeration systems and heat pumps. Use the humidity/temperature probe to measure the relative humidity and air temperature (for this measurement please order two humidity/temperature probes). The heating and cooling output are automatically calculated in the compatible measuring instrument.
