DMT242 Series

Dewpoint Transmitters
Measuring: -60 °C to +60 °C (-76 ... +140°F)
w/ accuracy of ±2 °C (±3.6°F)
Compatibility: DM70 Model
Models: DMT242
Manufacturer: Vaisala

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 film polymer sensor and auto-calibration software. 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.
