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.

Product Features

  • Fundamental, accurate and drift-free measurement
  • Remote sensor
  • Open design allows remote sensor to be mounted into a sample flow or simply placed in an environment to be monitored
  • -40 to +90°C dew-point range with ±0.1°C accuracy
  • Data logging to USB or SD card
  • 'FAST' guarantees frost formation below 0°C
  • Sensor operates in pressures up to 20 barg
