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
