New Humidity and Temperature Probe from Vaisala

The Vaisala HUMICAP^® Humidity and Temperature Probe HMP155 is designed to measure humidity and temperature, especially in meteorological applications.

The HMP155 has a new-generation Vaisala HUMICAP^®180R sensor, which provides long-term stability and withstands harsh environments well. The probe structure is solid and the sensor is protected with a sintered teflon filter, giving maximum protection against liquid water, dust, and dirt. An additional temperature probe is also available enabling fast measurement response in environments with rapidly varying temperatures.

The HMP155 incorporates a patented warmed probe option that is designed for reliable measuring in environments where humidity is near saturation. As the sensor head is warmed continuously, the humidity level inside it stays below the ambient level, which reduces the risk of condensation forming on the probe.

The HMP155 is especially desgined for use in meteorological applications, such as synoptic and hydrological weather stations, aviation, and road weather. It is also suitable for a wide range of instrumentation, for example, recorders, data loggers, and laboratory equipment and monitoring.
