Long-term stabilityVaisala Humidity and Temperature Transmitter HMP155 uses the proven Vaisala HUMICAP180R sensor that has excellent stability and withstands well harsh environments. The probe structure is solid and the sensor is protected by default with a sintered teflon filter, which gives maximum protection against water, dust, and dirt.Warmed probe and high humidity environmentMeasuring humidity reliably is challenging in environments where humidity is near saturation. Measurements may be corrupted by fog, mist, rain, and heavy dew. A wet probe may not give an accurate measurement in the ambient air. This is an environment to which Vaisala has designed this patented, warmed probe for reliable measurements. As the sensor head is warmed continuously, the humidity level inside it stays below the ambient level. Thus, it also reduces the risk of condensation forming on the probe.Fast measurementsWith its fast response time, the additional temperature probe for Vaisala Humidity and Temperature Transmitter HMP155 is ideal for measuring in environments with changing temperatures. The membrane filter speeds up the relative humidity measurement.KeyLong lifetimeProtecting the sensor from precipitation, and scattered and direct solar radiation increases its lifetime. Thus, Vaisala recommends installing HMP155 in one of the following radiation shields: DTR503, DTR13, or Stevenson screen. For the additional temperature probe, an installation kit is available for Vaisala DTR502 Radiation Shield.CalibrationThe probe can be calibrated using a computer with a USB cable, with the push buttons, or with the MI70 indicator. |
