General information

Accuracy

  • Humidity ± 2 %rh 10...90 %rh
  • Temperature ± 0,2 K with voltage
    ± 0,3 K with current


MELA® humidity/-temperature sensors in the PC, PK and RC series are compact, versatile sensors in a rod-type design. They are available with a 1.5 m connecting cable (PC series), without cable (PK series) or with a robust aluminium connecting head and terminal screws (RC series).

For extreme applications (near the sea, desert, mountains, areas with high air speed etc.) we recommend our stainless steel sinter filter
