RELATIVE HUMIDITY AND AIR TEMPERATURE Manufactured By: Vaisala and YSI
The relative humidity and air temperature sensor is compact and easy to use. The relative humidity element is a hygroscopic capacitive type and is fully interchangeable. These elements never need calibration. Instead, elements can be easily replaced without the expense and inconvenience sometimes associated with the calibration process. The membrane filter/mechanical housing of the sensor protects it from dust and dirt. Includes YSI 44034 Themilinear Bead for air temperature measurement.
