Model 225 Relative Humidity and Temperature Sensor

The Model 225 Relative Humidity and Temperature Sensor features a laser trimmed capacitive sensor for accurate relative humidity measurements. The chip is user replaceable and requires no calibration.

The 0 to 1 Vdc output can be easily connected to a data acquisition system or data logger such as the such as the Neon and Starlog Data Loggers. A membrane filter protects the sensor from dirt and dust but it should be mounted in a solar radiation shield when placed outdoors. A 3 meter detachable cable assembly is included.
