Testo High-Precision Humidity/Temperature Probe Head
The Testo 0636 9770 High-Precision Humidity/Temperature Probe Head is engineered for professionals who demand exceptional accuracy in humidity and temperature measurement. Designed to connect seamlessly to the Testo universal Bluetooth® or cable handle, this probe head allows for precise, parallel determination of relative humidity and air temperature, along with calculations for dew point, wet bulb temperature, and absolute humidity.
Equipped with Testo’s long-term stable, high-precision humidity sensor, this probe head achieves an accuracy of ±(0.6% RH + 0.7% of measured value) between 0 and 90% RH. Each sensor is traceable to international humidity standards such as ILAC, PTB, and NIST, ensuring reliable and repeatable results in demanding measurement environments.
Ideal for use in laboratories, cleanrooms, HVAC systems, and critical industrial processes, the probe head delivers consistent accuracy, even during long-term monitoring. Its intelligent calibration concept allows users to send in only the probe head for calibration, ensuring continuous operation of your measuring instrument and minimizing downtime.
