DRYCAP® Hand-Held Dewpoint
The Vaisala DRYCAP® Dewpoint
Transmitter DMT242 provides
reliable and stable measurements
for industrial dryer applications. It is
designed for extreme conditions.
DMT242 incorporates the Vaisala
DRYCAP® thin fi lm polymer sensor
and auto-calibration software.
The standard sensor choice for
dry gases and desiccant dryers is
DRYCAP® 180M and for more humid
applications such as refi geration
dryers, a DRYCAP® 180S sensor.
Both the sensors are immune to
particulate contamination, water
condensation, oil vapor and most
chemicals. Because the sensor
withstands condensation, its
performance is unmatched for
low dewpoint applications that
experience process water spikes,
such as pipeline condensation during
a system failure or start-up.
|The auto-calibration software works
on-line while the process is running.
If the measurement accuracy is not
confi rmed, corrections are made
automatically. The DMT242 adjusts
the measurement, corrects dry-end
drifts and continues to function.
Calibration occurs quickly, and
with corrections so minor, it will go
Compact, rugged and
Due to its compact size, DMT242 is
quickly and easily installed in tight
Users can perform a fi eld-check by
using the Vaisala DRYCAP® Hand-
Held Dewpoint Meter DM70. The
transmitter can be sent to Vaisala
Service for NIST traceable calibration.
The recommended calibration
interval is every two years
