These compressed air dewpoint
monitors have been designed to
offer the highest level of reliability
and accuracy available in such
systems. They are fully NIST
traceable and employ a chilledmirror
sensor, the most accurate
dewpoint sensing scheme available,
to deliver consistent drift-free
measurements without regular
calibrations or sensor replacement.
These compressed air monitors are
complete dewpoint measuring
systems. The ruggedized aluminum
NEMA 12 (IP55) enclosure houses
the sensor, control circuitry
(including flow control) and is easily
wall mounted to conserve space.
Only the sample line and power
connection are needed for the
system to be operational.
The monitors also offer a
programmable automatic balance
control (ABC) cycle that corrects for
the light-reducing effects of mirror
contaminates and allows for
continuous monitoring and virtually
maintenance-free operation.
