FEATURES
Measures a wide humidity range of 5 to 95% RH.
High accuracy. The nominal accuracy for the CHS-UPR and -UPS within ±3% RH.
The temperature characteristics are stable over a wide range.
Humidity-sensitive characteristics exhibit virtually no hysteresis.
Highly cost-effective and compact, requiring extremely little mounting space.
Low current consumption.
Outputs DC.1V at 100(%)RH; relative humidity can be read directly with a voltmeter.
It is of an all-in-one construction that integrates all needed circuitry and operates on a 5V power supply.
