The new PeakTech 5039 is an affordable thermo-hygrometer for the simultaneous measurement and display of ambient temperature and humidity in a compact design. Additionally, this model offers wet bulb temperature measurement, which represents the lowest temperature that can be achieved through direct evaporative cooling. Furthermore, this model can measure the dew point temperature, which must be reached for fog or dew to form from water vapor. All measurement values can be easily read on the large LCD display with backlighting. This cost-effective and compact measuring device is ideal for use in the construction sector, building technology, or heating and air conditioning technology.
