Multifunction Psychrometer with ISO calibration certificate
Measures relative humidity (% RH) and ambient room temperature (°C / °F) / Calculates dew-point and wet-bulb temperatures (°C / °F) / Features hold and extreme value measurement functions

The psychrometer is an environmental tester or diagnostic measuring device used for indoor climate and environmental monitoring. In addition to measuring relative humidity and ambient room / dry-bulb temperature, the meter calculates dew-point and wet-bulb temperatures in degrees Celsius (°C) and Fahrenheit (°F). Thus, heating, ventilation and air conditioning (HVAC) installations and HVAC system performance assessments are key applications of the psychrometer. Measurements of relative humidity and ambient room / dry-bulb temperature are made directly by built-in sensors. Dew-point and wet-bulb temperatures are calculated based on the measurement values transmitted ​​by the sensors.

Featuring a large, backlit display and six-button operation, the psychrometer is both easy to read and easy to use. The environmental tester is equipped to take one-time measurements on the spot as well as to monitor climate changes over time. The automatic shutdown function can be disabled when taking long-term measurements. There is also a thread on the back of the environmental tester to allow the measuring instrument to be mounted on a tripod. The extreme value measurement function can be activated during long-term monitoring to determine the minimum or maximum values ​​over a desired period of time.
