The Testo 0636 9730 is a humidity/temperature probe head, used to determine relative humidity and air temperature in indoor areas. Please note, this configuration does not include a Bluetooth or wired handle. Also, this cannot be used on its own - it must be used with a Testo multifunction instrument. Please do not use the probe 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 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.
