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.

Chapter 1, General Information, provides general notes for the manual and the Humidity and Temperature Probe HMP155. Chapter 2, Product Overview, introduces the features, advantages, and the product nomenclature of the Humidity and Temperature Probe HMP155. HMP155.

Protected from powerful water jets from any direction. 1 Defined as ±2 standard deviation limits. Small variations possible (see also the calibration certificate).

It uses a HUMICAP ® 180R capacitive thin film polymer sensor to measure RH over the 0 to 100% RH range. A PRT measures temperature over the -80° to +60°C range. This rugged, accurate temperature/RH probe is manufactured by Vaisala.
