Description

PCE-WB 20SD industrial safety meter with data logger function for an objective assessment of working conditions in extreme weather conditions The PCE-WB 20SD industrial safety meter measures WBGT values in indoor and outdoor areas, the black globe temperature, humidity, air temperature, wet ball temperature and the dew point temperature. This makes the OSH meter the ideal instrument for objectively determining working conditions in extreme weather conditions, as well as appropriate levels for physical activities. The integrated data logger function enables the storage of up to 99 measured values in intervals of 1 - 3,600 seconds or by pressing a button on the safety measuring device. The recorded data can be read from the SD card or via USB/RS 232 on a PC and further analyzed in Excel.
