The HMP155 is engineered to deliver precise data in high humidity climates where moisture is near saturation, in environments with changing temperatures, and in harsh environments where measurements may be corrupted by chemicals, fog, mist, rain, and heavy dew.

Long-term stability
The HMP155 is engineered to withstand harsh environments. Its design features a solid probe structure protected by a sintered teflon filter that delivers maximum protection and excellent long-term stability around chemicals, water, dust, and dirt.
Accuracy under any conditions
The HMP155 is reliable under drastic temperature variations down to -80°C ( -112°F). Warmed probe technology delivers accurate humidity measurements even under condensing conditions. This also helps in reducing chemical contamination and in minimizing drift.
Traceable factory calibration
Each HMP155 is adjusted and calibrated individually at the Vaisala factory. To ensure high accuracy over the whole measurement range, standard six-point calibration is performed covering humidity ranges from completely dry to nearly saturated conditions, and applied references are SI-traceable.
