PEAKMETER PM6508 Digital Temperature & Humidity Meter

This is a battery meter for measuring relative humidity and temperature. It can display three types of temperatures around the sensor’s air via several convenient procedures: the ambient temperature, the dew‑point temperature, and the wet‑bulb temperature.

Summary: Battery‑powered digital meter that provides precise ambient, dew‑point and wet‑bulb temperature readings together with 0‑100% RH measurement, featuring data hold, back‑light, min/max tracking, and logging of up to 100 data groups.
