RHB-1500-C1S2,
$4940, shown
smaller than
actual size.
This portable dew point
hygrometer integrates the accuracy
and reliability of the OMEGA®chilled
mirror with the battery life and
ruggedness required for field use.
The RHB-1500-C portable chilledmirror hygrometer has all the
standard features, such as drift-free
NIST-traceable accuracy, low
maintenance, high durability, and
ease of use—in a system that is
ideally suited for the demands of
field use. Whether you use the
RHB-1500-C as a field transfer
standard or to spot-check your
process air dryness or dew point,
you'll find this system provides
trouble-free operation.
The RHB-1500-C is a self-contained
system. Not only is field assembly
not required, but also there is not a
need to carry around a myriad of
individual components such as
control boxes, sensors, cables,
pumps, and power cords. Simply
attach the sample line, adjust the
flow (with the integral flowmeter),
Hu-55
and turn on the power. Within
minutes you'll be collecting field dew
point data with the same
chilled-mirror accuracy of a
lab-standard hygrometer. And with a
nominal battery life of 12 hours, the
RHB-1500-C lets you collect for the
entire shift or spot-check your
processes for several days.
