METTLER TOLEDO - InPro 5500i 溶解二氧化碳電極(啤酒製程應用)

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

The InPro 5500i has ISM‘s pre-calibration and Plug and Measure functions ensure 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.

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