PCE 444 Temperature and Humidity Meter
The PCE-444 climate meter (
) is a handheld mini-thermohygrometer that measures air temperature, relative humidity, dew point temperature, and wet-bulb temperature
The PCE-444 is a combined digital hygrometer and digital thermometer used to measure air temperature, relative humidity, dew point temperature, and wet-bulb temperature. This portable, pocket-sized handheld mini-thermohygrometer allows you to quickly and easily determine indoor environmental conditions. Applications include climate monitoring in refrigerated trucks, warehouses, construction sites, and HVAC systems, where excessive humidity, condensation, and uneven temperatures can lead to mold, spoilage, and health risks.
