I7000 & 7400 (Hygrosmart)

 Interchangeable Sensor Module for Relative Humidity
The concept of the I7000 (Hygrosmart) is its interchangeability without the need of a recalibration. The small size allows its integration in any equipment while the plug-and-play system allows fast replacement even by non-skilled staff.







Product Features

  • Interchangeable without recalibration
  • Measurement of relative humidity
  • Operating range: RH 0–100%, Temperature -40 to +95°C
  • Output signal: 0–1 VDC
  • Capacitive thin film humidity sensor
  • Sensor response time: <10 seconds
  • Possibility of linearization for a specific isotherm (on request)
  • Output signal linearised and numerical compensation of the drift in temperature of 0–60°C
