The P-14 humidity sensor was specially developed to satisfy the wide range of applications in the heatingventilation
and airconditioning sector. 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 for selecting the electrical connections provides users
with ideal opportunities for implementing their own sensor design without limitation.
