This stainless steel industrial probe is especially suitable for high temperatures, demanding industrial environments and areas where hygiene plays an important role. The probe measures humidity and temperature and calculates the dew/frost point.


  • Range of measurement: -100â¦200 °C, (screw-in probe; -50â¦200 °C) / 0â¦100 %RH
  • Digital interface (UART) and scalable analog outputs, 0â¦1 V
  • Standard output scaling: 0â¦1 V = -40â¦60 °C / 0â¦100 %RH
  • Adjusted at 23 °C and 10, 35, 80 %RH
  • Cannot be operated with 2-wire transmitters
