Humidity and Air Temperature Sensor TS251 T

The combined humidity and temperature sensor Model TS251 T is designed for ambient measurement.

The humidity measurement is based on the dielectric variation of a high stability solid state capacitor, while that of temperature by a high accuracy platinum resistance resistance.

The sensor is protected by means of a filter, giving it high resistance to dust and contaminants and can be used for extended periods of time without recalibration.

The electronics integrated to the sensor, allows an amplied signal from 0 to 4 V suitable for recorders, weather stations, etc. A watertight cabinet houses the electronics, and is provided with an anchor suitable for attaching to a sunscreen and mounting arm.
