METTLER TOLEDO InPro 5500i CO₂ Sensor for Beverages

The METTLER TOLEDO InPro 5500i enhances industry-proven thermal conductivity CO2 measurement by providing increased reliability, leading to greater operational uptime.

Less Maintenance, Greater Reliability

Dissolved CO2 in-line sensor for breweries and carbonated soft drinks process control

Intelligent Sensor Management (ISM) technology offers pre-calibration and Plug and Measure functions for fast, error-free measurement point start up. The Dynamic Lifetime Indicator and the Adaptive Calibration Timer enable predictive maintenance planning keeping the sensor at peak performance at all times. A choice of process connections ensures easy installation.

The InPro 5500i sensor can be combined with an M400 transmitter for a single measurement loop or with an O2 sensor using the M800 multi-channel transmitter for a complete dual O2 / CO2 loop.
