Vaisala DMT242 Dewpoint Transmitter

Vaisala DMT242 Dewpoint Transmitter  provides reliable dewpoint measurement in dry processes such as industrial dryer applications. The Vaisala DMT242 incorporates the Vaisala DRYCAP® thin film polymer sensor and auto-calibration software, which has a proven track record for dewpoint measurement for accuracy and stability of reading. The standard sensor choice for dry gases and desiccant dryers is DRYCAP® 180M and for more humid applications such as refrigeration dryers, a DRYCAP® 180S sensor.  Both the sensors are immune to particulate contamination, water condensation, oil vapor and most chemicals. Because the Vaisala DMT242 withstands condensation, its performance is unmatched for low dew point applications that experience process water spikes, such as pipeline condensation during a system failure or start-up.


Note that the Vaisala DMT242 dewpoint transmitter has been discontinued.  Please contact Fluidic for alternatives (note that the Vaisala DMT152 Compact Dewpoint Transmitter would be a typical alternative).
