Features
Simple PC-based calibration using the unit’s push buttons or with the MI70 indicator. Accessed via USB cable connection.
Weather-proof housing (IP66) that ensures continuous, safe data capture and reporting.
Flexible output choices that include Voltage, RS-485, resistive Pt100.
Optional warmed probe technology ensures accurate measurement and better long-term stability in high-condensing environments.
Optional chemical purge function regularly cleans the humidity sensor chip to reduce sensor drift caused by pollution-based chemical vapors — ideal for road and maritime installations.
Optional fast temperature probe for quicker, accurate temperature measurement. Compatible with liquid bath calibration.
