BASIC INFO
Michell S8000 Remote High Precision Chilled Mirror Hygrometer
The S8000 Remote has all the great features of the other S8000 Series chilled mirror hygrometers, but with a convenient and compact remote sensor design.
The field-proven sensor boasts upgraded temperature control for extremely accurate dew-point measurement. Coupled with the standard ±0.1°C accuracy ambient temperature sensor, it provides fundamentally derived, high precision relative humidity readings necessary for validating the results of environmental tests.
