S4000 RS & TRS Precision Dew-point Hygrometers |
|
|
The S4000 range of high precision Cooled Mirror Dew-point Hygrometers offer unmatched accuracy and reliability in dew-point measurement and calibration. The powerful three-stage Peltier thermoelectric heat pump, coupled with integrated auxiliary refrigerant cooling, gives an effective measurement range down to -85°C dew point for the S4000 RS and to
-100°C dew point for the S4000 TRS.
