Assessing thermal comfort, based on the parameters of air temperature and relative humidity, is important for the well-being of the person using a room. Pleasant room conditions are a primary factor in the planning, selection and configuration of a heating and ventilation system.
Humidity can be specified as a relative or absolute value. Recommendations for the relative humidity in a room range between a minimum of 30% and maximum value of 65%. The humidity limit outside this range is either not reached or exceeded.
All of our temperature/humidity measuring instruments and probes include the humidity sensor developed and patented by Testo; it is both stable long-term and condensation-resistant.
The testo 625 is a compact instrument with integrated humidity probe. It displays relative humidity, wet bulb temperature or dew point, and temperature. For measurements in difficult to reach places, the humidity probe can simply be removed and attached to the handle with a probe cable (accessories). Alternatively, the readings can be transmitted wirelessly by radio over great distances from the probe to the measuring instrument.
