Extech RHT510 Hygro-Thermometer Psychrometer
It is important to measure & control moisture and relative humidity in occupied spaces. The presence of moisture and dirt can cause molds and other biological contaminants to thrive. Relative humidity levels that are too high can contribute to the growth and spread of unhealthy biological pollutants. Humidity levels that are too low, however, may contribute to irritated mucous membranes, dry eyes and sinus discomfort.
