HygroMer HH1-SK - The perfect Sensor for decontamination applications with Hydrogen Peroxide

 

Sterilization & decontamination - humidity sensor

 

•Designed for the use in hydrogen peroxide sterilization processes and harsh environments

•Sophisticated mechanical design and superior chemical resistance

•Additional protection cage for condensation prevention of the Polymer itself

 

A capacitive polymer humidity sensor is a special type of humidity sensor based on the use of polymeric materials to detect changes in humidity. The sensors utilize the properties of polymers that react to moisture and thereby influence the capacitance of the sensor. The evaluation electronic convert the capacitive value into humidity value.

The HygroMer HH1-SK sensor stands for an advanced chemical resistance and can be quoted for chemical and industrial measurements.
