Unit simultaneously displays humidity or dew point and temperature. One of the newest and fastest humidity sensors ever developed displays full-range humidity changes in 5-30 seconds. It records wide humidity variations on a second-to-second basis. Monitor labs, clean rooms, food processing, and all humidity-sensitive manufacturing areas with this high-resolution unit. Relative humidity resolution is 0.01%, accuracy is ±3% RH, and range is 10.00 to 95.00% RH. Dew Point is a calculated measurement, resolution is 0.01°, accuracy is sum accuracy of humidity and temperature.
