Traceable® 4392TR Relative Humidity Thermohygrometer with Dew Point

Traceable® 4392TR Relative Humidity Thermohygrometer with Dew Point

This pocket‑sized thermohygrometer measures full‑range relative humidity, ambient temperature, and calculates dew point. The compact instrument uses an electronic capacitance polymer film sensor that is not affected by condensation, allowing accurate readings up to 100% RH. The dual‑line display simultaneously shows humidity and either current temperature or dew point.

Quickly recall minimum and maximum RH and temperature values, and freeze data readings with the press of a button. The unit automatically powers down after 20 minutes of non‑use to conserve battery life. Each meter includes an individually numbered NIST‑traceable certificate from an A2LA‑accredited calibration laboratory.
