HN-C Series Temperature/Humidity Meters

Data_Sheet
The HN-C series is reliable and accurate temperature/ humidity meter with the measuring humidity range of 0 to 100%RH by using a new developed humidity sensor. Models with temperature output of 3-wire type Pt100 is available.
Wall-mounting type, separated type and insertion type are prepared for various applications. Heat-resistive separated type is available for using in the environment of -40 to 180°C.,

Features

  • Improved repeatability and reliability by a new developed humidity sensor
  • Measurement of relative humidity 0 to 100%RH by capacitance type humidity sensor
  • Three types of wall-mounting type, separated type, heat-resistive separated type and insertion type (soft type and hard type) are prepared for various applications.
  • Heat-resistive separated type can be used in the environment of -40 to 180°C
  • Easy maintenance by complete interchangeable sensors
  • DIN rail installation enabled (except insertion type)
  • CE conformance
