Vaisala DMP5 Dew Point and Temperature Probe


Vaisala DRYCAP® Dew Point and Temperature Probe DMP5 is designed for in-line humidity measurement in industrial drying applications with high temperatures and a wide dew point range. The long and robust steel probe and optional installation flange allow easy installation with adjustable depth to reach through insulation, for example in ovens.


Product Details

DMP5 incorporates the Vaisala DRYCAP® sensor, which is accurate, reliable, and stable. The sensor is condensation-resistant and immune to particulate contamination, oil vapor, and most chemicals. Sensor warming minimizes the risk of condensation accumulating on the sensor. If the DRYCAP® sensor does get wet, it dries rapidly and recovers its swift response time. In low-humidity conditions the sensor will auto-calibrate to ensure accurate measurement.
