Sensors
I7000 & 7400 (Hygrosmart)
Interchangeable Module for Relative Humidity
The I7000 (Hygrosmart) Series is interchangeable without the
need for recalibration. The small size allows its integration
in any equipment while the plug-and-play system allows fast
replacement even by non-skilled staff.
Highlights
• Interchangeable without recalibration
• Sensor response time: <10sec
• Linearization for a specifi c isotherm on request
• Can be used up to peak temperatures of 95°C (200°F)
