Testo Humidity/Temperature Probe (Digital, Wired)
The Testo 0636 9732 Digital Humidity/Temperature Probe (Wired) delivers reliable and precise measurements of relative humidity and air temperature in HVAC ducts, storage areas, refrigerated rooms, laboratories, and work environments.
Equipped with Testo’s long-term stable capacitive humidity sensor, this probe ensures consistent accuracy of ±2% RH (5 to 90% RH) and ±0.5 °C across a wide measurement range of 0 to 100% RH and -20 to +70 °C. In addition, the probe calculates dew point, wet bulb temperature, and absolute humidity, providing a complete picture of indoor air quality and system performance.
The fixed cable connection ensures uninterrupted communication between the probe and your compatible Testo multifunction measuring instrument (such as Testo 400, 440, or 480). The intuitive long-term measurement menu enables structured data capture with time-based logging and easy trend visualization.
With the ergonomic handle button, you can save readings or control measurement series directly from the probe. The universal handle system allows you to interchange various Testo probe heads, minimizing equipment needs while maximizing versatility.
Built with the intelligent calibration concept, this digital probe allows calibration of the probe head independently of the instrument — ensuring continuous operation without downtime.
