As with all oxygen sensors from METTLER TOLEDO also the ISM sensors fulfill highest requirements for hygienic design in compliance with  EHEDG and 3-A standards. The proven maintenance concept with membrane body and replaceable inner body is continued with all i-type sensors.

Features and Benefits

High measurement stability

The new 3-electrode principle with its separated platinum anode for higher signal stability

Enhanced diagnostics

Permanent sensor monitoring with ISM technology reduces the risk sensor failures

Predictive maintenance

The enhanced diagnostics allows for better maintenance planning "as few as possible, as often as necessary"

High process safety

FDA compliant materials of construction and easy-to-clean high-polished surface (N5 grade) to satisfy increasing regulatory requirements.

Reduced service time

Thanks to the easy-to-replace membrane body and quick-disconnect interior body.

Long sensor lifetime

Durable and rugged sensor design for increased resistance to harsh environments

Installation in hazardous zones
