HC2-CO4/HC2-CO5 Compact Humidity Probe for Tight Spaces

New product
More info

This miniature probe is used for humidity and temperature measurement in confined spaces. It also calculates the dew and frost point.


  • Range of measurement: -40â¦85 °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
