Stability at Low Dew PointsThe Vaisala DRYCAP
sensor is immune
to particulate contamination, water
condensation, oil vapor, and most
chemicals. The sensor tolerates
condensation and recovers perfectly if
exposed to liquid water. Fast reaction
time and stability make its performance
unmatched in dynamic and low dew
point applications. Outstanding stability
ensures a long calibration interval.
Sensor Purge Minimizes Contaminant EffectsIn environments with high
concentrations of chemicals and cleaning
agents, the sensor purge option helps
maintain measurement accuracy
between calibration intervals.
The sensor purge involves heating the
sensor to remove harmful chemicals. This function can be initiated manually or programmed to occur at set intervals.

Flexible Connectivity Options The probe operates as a standalone
digital Modbus RTU transmitter over an
RS-485 serial bus, and it can also be
connected to Indigo transmitters and the
Indigo80 handheld indicator. For easy
access to field calibration, device
analytics, and configuration functionality,
the probe connects to Vaisala
Insight software for Windows
.
