PCE-444 Handheld Hygrometer
Handheld mini climate meter measures air temperature, relative humidity, dew point temperature and wet bulb temperature
PCE-444 is a combination digital hygrometer and digital thermometer used to measure air temperature, relative humidity, dew point temperature and wet bulb temperature. This portable handheld pocket-sized mini thermo-hygrometer allows for the quick and easy determination of indoor ambient environmental conditions. Applications include monitoring climates of refrigerated trucks, warehouses, construction sites and HVAC installations, where excess moisture, condensation and uneven temperatures can create mold, spoilage and health hazards.
