Reliable trace detection of oxygen

METTLER TOLEDO’s InPro 6900i G combines high measurement performance with the latest capabilities of the ISM technology. Designed for best performance at the ppm level, they are easy to maintain and allow for high operational availability.

Thanks to the integrated ISM technology with Plug and Measure capability, installation is much easier. New possibilities for maintenance planning are possible thanks to automated self diagnosis and asset management. Together with the iSense, always stay one step ahead of maintenance tasks.

Features and Benefits

Enhanced diagnostics
Permanent sensor monitoring with ISM technology reduces the risk sensor failures.
 
Predictive Maintenance
The DLI (Dynamic Lifetime Indicator) assesses in real-time the remaining lifetime of the sensor.
 
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
