InPro 6970i series – a sensitive oxygen sensor

With the InPro 6970i series, Mettler-Toledo Ingold introduced a new line of optical sensors for the measurement of dissolved oxygen in Food & Beverage. Based on a chemo-optical technology, the InPro 6970i sensor offers significant advantages for the brewing industry. High operational availability, combined with excellent measurement quality is the perfect answer to the most demanding brewery requirements such as increased product yield and guaranteed minimized level of oxygen in beer.

The InPro 6970i optical sensor with integrated ISM technology uses fluorescence technology to accurately and reliably determine the dissolved oxygen content during the process. This innovative technology, combined with INGOLDs long-standing experience in the measurement of analytical parameters such as oxygen, conductivity, turbidity and pH was refined to produce the most advanced measurement system for industrial use and set a new standard of excellence for enhanced performance and ease of use.

Equally important for the brewer is the minimal maintenance required. The OptoCap can be replaced by the user without any specialist know-how. The optical sensor does not need any electrolyte or polarization resulting in very easy maintenance. This improves its operational availability and significantly reduces the risk of inadvertent handling errors. Long calibration intervals, easy and fast calibration routines result in high operational availability of the system.

The InPro 6970i contains ISM (Intelligent Sensor Management) technology which monitors status information in real time and increases the process safety. Additional status information like DLI ( Dynamic Lifetime Indicator) or ACT (Adaptive Calibration Timer) is processed in the sensor head, providing the user with real-time warnings when early signs of end-of-life of the optical cap appear or when calibration is necessary.
