Digital Humidity Sensor HYT 221 – for critical application areas

 

Splash water proof   | with protection filter | Outdoor-suitable

 

The round stainless steel casing can be easily fitted into housing openings and can be sealed against the wall with the use of O-ring. In combination with the waterproof membrane filter, it results into an assembly that is splash water proof and enables a sealed housing construction while providing a high dynamic responsiveness. 

Typical areas of application are humidity measurement in the sauna, applications in outdoor areas or industrial applications in the field of drying systems.
