Product
The P-14 humidity sensor was specially developed to satisfy the wide range of applications in HVAC, tests and
measurement, white goods and industrial field. By the consistent use of state-of-the-art production technologies
and our extensive know-how in the field of high performance polymers, we have succeeded in producing a high
quality sensor with an almost linear characteristic. The possibility of selecting the electrical connections provides
users with ideal opportunities for implementing their own sensor design without limitation.

Advantages
High humidity stability
Low drift
Condensation resistant – fast recovering time after dewing,
and at high dew point temperatures as well
High chemical resistance
Wide temperature operating range
Various wired solutions available
