In combination with the testo 635, the robust humidity probe measures the humidity and temperature of the air. Because the probe can be used up to 125 °C, it also enables measurements in air exhaust ducts. In addition, it is suitable for measuring the material equilibrium moisture content, for example in bulk materials.
