Wohler IR Hygrotemp 24

Wohler IR Hygrotemp 24 Wohler IR Hygrotemp 24 Indoor Air Quality The Wohler IR Hygrotemp 24 is a battery-driven multi-use measuring instrument to determine air humidity, air temperature and surface temperature. Furthermore, it calculates the dew point, the wet bulb temperature and the difference in the dew point and the surface temperature. Now, you can evaluate the indoor air quality and the mold potential with only one instrument. Three single values are displayed on the screen at one time. If there are poor lighting conditions, the display backlight can be turned on. The activated laser can determine the spot for the surface temperature measurement.
