13308 Pen Type Thermo-Hygrometer FAQs
Why is the Thermo-Hygrometer not showing humidity?
The humidity went above the maximum range or dew point was reached and moisture formed on the sensor. Allow the unit to dry in a low humidity environment until it starts reading again. At very low humidity the unit will stop reading until the humidity rises. If the temperature goes below freezing (0.0°C, 32°F) the humidity will no longer be displayed until the temperature rises above freezing.
Will the Pen Type Thermo-Hygrometer get accurate readings while clipped on my pocket?
There will always be moisture temperature from proximity to the body that will affect the accuracy of the Hygrometer. It is best to use it in an area with air circulation is away from the body.
