This pocket-sized thermohygrometer measures full-range relative humidity, temperature from -4 to 122°F (-20 to 50°C), and calculates dew point. Compact design features an electronic capacitance polymer film sensor - not affected by condensation. Quickly recall minimum and maximum RH and temperature values, and freeze data readings with the press of a button. The dual-line display simultaneously shows humidity and either current or dew point temperature. Unit turns off automatically after 20 minutes of non-use to conserve battery life.

Traceable® products have an individually-numbered Traceable® certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognised national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.
