Sensor operates in pressures up to 20 barg

The S8000 Remote is a compact chilled mirror hygrometer with a remote sensor. It provides it provides fundamentally derived, high precision relative humidity readings necessary for validating the results of environmental tests.

It offers a wide measurement range from the equivalent of < 0.5 to 100% RH (dew point range: –40 to +120°C) at temperatures up to +120°C. The S8000 Remote features a new sensor design, incorporating a high precision 1/10DIN PT100 to provide ±0.1°C accuracy of dew-point measurement. Combined with the ±0.1°C accuracy temperature measurement sensor, the RH measurement accuracy of the S8000 Remote is better than other products currently available on the market.
