In-line amperometric sensors (also called polarographic sensors) for gas-phase oxygen measurement in chemical processes combine high operational uptime with excellent performance. Without the need for an expensive gas sample conditioning system, METTLER TOLEDO's gas-phase oxygen sensors can be installed directly in the process and sensor maintenance can be performed without process interruption.

METTLER TOLEDO offers a unique, easy-to-use and reliable solution for challenging applications such as N2 blanketing, inertization and off-gas monitoring in hazardous or non-hazardous applications.

Oxygen sensors with integrated Intelligent Sensor Management (ISM) functionality feature advanced diagnostics, and Plug and Measure for fast sensor start-up.
