The Vaisala HUMICAP° Humidity and Temperature Transmitter HMT335 has a long stainless steel probe designed for high temperatures.

The Vaisala HUMICAP° Humidity and Temperature Transmitter HMT337 is delivered in one of three configurations:
• Basic: non-warmed probe for moderate humidities
• With a warmed probe: for near-condensing conditions and dew point measurement
• With a warmed probe and an additional temperature sensor: for near-condensing conditions and relative humidity measurement

 

True humidity readings in conditions of condensation
The Vaisala unique warmed probe head provides fast and reliable measurement in environments where humidity is near saturation. The warming prevents condensation from forming on the sensor.

As the probe head is warmed, the humidity level inside the head stays below the ambient level. With accurate temperature measurement, the ambient dewpoint can be calculated precisely.

If the relative humidity value is needed, an additional temperature sensor head is used. The measured ambient temperature provides the compensation for calculating the relative humidity and other humidity parameters.
