Michell Instruments S8000

Remote Chilled Mirror Hygrometer

The Michell S8000 Remote is a chilled mirror hygrometer that measures dew point using direct condensation on a controlled mirror surface. It provides a dew point range from −40 °C to +120 °C with an accuracy of ±0.1 °C. The sensor operates at pressures up to 20 barg and measures temperature with a 4 wire Pt100 sensor at ±0.1 °C accuracy. The instrument supports data logging through USB Ethernet and SD card interfaces.
