Use the humidity/temperature probe with the compatible testo multifunction measuring instrument (please order separately) to measure relative humidity and air temperature. Dew point, wet bulb temperature, absolute humidity as well as the heating and cooling output are calculated at the same time.
Measurement Values are transmitted via a connection cable to the testo 440.
Thanks to a large measuring range of 0 to 100% RH and -4 to +158°F, you can measure relative humidity and air temperature reliably.
Intuitive: clearly structured measurement menu for long-term measurement and parallel determination of the relative humidity and air temperature in indoor areas
Precise: calculation of wet bulb temperature, dew point and absolute humidity
Convenient: Universal wired connection handle can easily be combined with other probe heads
Intelligent calibration concept. Only the probe tip needs to be sent for calibration.
