A ‘workhorse’ in many calibration
laboratories and industrial settings.
The S8000 RS Precision Chilled Mirror Hygrometer from Michell Instruments, measures dew points down to -90°C (0.1ppmV)
with an accuracy of ±0.1°C. However, unlike many other chilled
mirror hygrometers in this class, no additional external cooling equipment is
needed to accurately reach these dry dew points. Designed to fit into a
standard 19” 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.

Although referred
to as ‘dew-point temperature’, chilled mirror hygrometers most often measure
the frost point because the temperatures are below freezing. However, in some
conditions, liquid water can exist as ‘super-cooled water’ in temperatures as
low as -40°C. Because the difference in condensing temperature
between water and ice can be as much as 10% of the reading, it’s essential to
know which phase you are measuring. The S8000RS uses Frost Assurance Technology
(FAsT) to ensure that ice, not liquid water, is present on the mirror surface
at low temperatures to ensure that your measurements are always a known
quantity.
