| Definition | A robust composite general purpose humidity and temperature sensor which utilises the Vaisala HUMICAP 180RC and a PT100 temperature sensor integrated within the relative humidity sensor. The sensor has high humidity durability, good long-term stability and good tolerance against chemical exposure. The sensor head is warmed by the integrated Pt100 temperature sensor to ensure the humidity level inside stays below the ambient level, to reduce the risk of condensation forming on the probe and corrupting the measurements. The instrument is also capable of measuring dew point, frost point temperature, wet bulb temperature, and mixing ratio. The instrument features a membrane filter to speed up the relative humidity measurement, for use in environments with fast changing temperatures. The sensor has applications in environments with high concentrations of chemicals due to the chemical purge and warmed probe features. The HMP155 measures humidity between 0 and 100% relative humidity, at an accuracy of +/- 1% for measurements between 0 and 90% relative humidity, and +/- 1.7 % for measurements between 90 and 100 % relative humidity, at ambient temperatures of 15 to 25 degC. At temperatures outside this range, humidity measurement accuracy ranges from 1.0 to 1.5 % relative humidity. The HMP155 measures temperature within an observational range of -80 to 60 degC, at an accuracy of between +/- 0.055 and 0.226 degC depending on the ambient temperature and output setting. | ||
