The new InPro6970i designed for brewery application sets a new standard for operational availability and measurement quality of your oxygen loop especially in the filler line. The optical oxygen sensors are easy and fast to maintain, leading to enhanced process safety and low cost of ownership. Reduced signal drift and faster response time compared to amperometric sensors guarantees maximum accuracy of the oxygen measurement and allow for enhanced process control.

High process safety
Maintenance redefined with ISM
Enhanced process control
The light source and the detector are both integrated in the sensor head. The unique ISM (Intelligent Sensor Management) technology is implemented in all optical sensors from METTLER TOLEDO. All system data including calibration and diagnostic information are stored in the sensor.
The METTLER TOLEDO sensors InPro6970i are based on the so call fluorescence quenching. The signal of the fluorescence is compared with a reference signal and the oxygen concentration is calculated from the time shift between these two signals. The oxygen concentration is displayed on the transmitter.
