Supplier: AMS Instrumentation & Calibration

The S8000 RS is a compact, stand-alone chilled mirror hygrometer that provides a boost for small calibration labs.


Since its launch in 2012, the S8000 RS from Michell Instruments has proved to be a popular reference instrument with smaller calibration laboratories enabling them to generate extra revenue by extending their service to humidity calibration. The reason? It is the smallest and lightest hygrometer in its class, which enables small calibration laboratories to extend their ranges – but without also needing to extend their premises. The easy-to-use instrument also suits in-house reference labs at larger organisations.

The S8000 RS Precision Chilled Mirror Hygrometer measures dew points down to -90°C (0.1ppmV) with an accuracy of ±0.1°C. However, unlike many other hygrometers in this class, no additional external cooling equipment is needed to accurately reach these dry dew points. Even without all the extra cooling equipment, the S8000's nearest competitor in performance weighs 28 kg more than the S8000. Designed to fit into a standard 17" rack, the S8000 is the most compact, convenient and – because it doesn't need extra equipment to work – the most cost effective hygrometer in its class.

This compact design was possible because of a sophisticated new optical system that detects very small changes in moisture condensed on the mirror surface. This guarantees high sensitivity and fast response when measuring low dew points.

With a high-contrast LCD touchscreen, the S8000 RS is easy to operate and interrogate. USB or Ethernet connections are supplied as standard to enable remote operation and data logging via a PC or network. As with all Michell chilled mirror hygrometers, the S8000 RS is available with a 5-point calibration, traceable to national standards, with UKAS accredited calibration available.
