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 +120°C dew-point range with ±0.1°C accuracy
  • Data logging via USB, Ethernet or SD card
  • 'FAST' guarantees frost formation below 0°C
  • Sensor operates in pressures up to 20 barg

The S4000 RC provides accurate measurement of dew-point, temperature and % RH from -85°C to +80°C dew point. The remote sensor is ideal for environmental monitoring.
optidew_401_501.htm Optidew
De Optidew 401 en de Optidew 501 zijn spiegeldauwpunt-meters, ontworpen om de originele Optidew instrumenten op te volgen. De Optidew 401 is een tafelmodel en vervangt de Optidew Vision. De Optidew 501 is geschikt voor muurbevestiging. Het is de opvolger van de Optidew transmitter en heeft optioneel een touch-screen, zoals bij de Optidew 401, voor lokale bediening. De Optidew 501 is ook zonder display te verkrijgen.
