PCE-WM1 Powerful Environmental Meter

Environmental Meter PCE WM1

PCE-WM1 is a multifunction environmental measuring device for determining relative humidity (%RH), absolute humidity (g/m³), air temperature, dew point temperature, and surface temperature (°C). This purely metric gauge comes complete with an external sensor probe to measure the surface temperature of various materials.

Environmental Meter PCE WM1 is widely used in the construction industry to assess building materials and working conditions. It is also used in the food industry to ensure product quality and freshness. Additionally, heating, ventilation, and air conditioning (HVAC) technicians rely on this meter to perform HVAC system performance checks.

The humidity sensor of PCE-WM-1 is calibrated by the manufacturer. Optionally, an ISO calibration certificate from an accredited calibration laboratory can be requested. See the Accessories tab for more details.
