The all-rounder for in-line oxygen measurement.

METTLER TOLEDO’s line of amperometric gas-phase oxygen sensors are well suited for a wide measurement range in a broad choice of applications. These in-line sensors provide excellent performance with minimum maintenance and do not require any gas sampling and pre-conditioning systems.

Features and Benefits

In-situ measurement
Measurements are fast and are performed directly in the process stream.
 
Accurate
Insensitive to moisture and dust, the membrane – covered sensing element is permeable to oxygen, not liquids.
 
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
