Calibration vessel O2

The optical sensor for measuring dissolved oxygen (DO) can be used with a 913 pH/DO meter or with a 914 pH/DO conductometer. The measuring principle of the sensor is based on luminescence quenching. The space-saving and maintenance-free sensor is suitable for DO measurement, for example in: Water quality control; Wastewater industry; Beverage production; Fish farming; This sensor is supplied with a calibration vessel. Where necessary, it is easy to replace the measurement cap (O2 cap) that contains the oxygen-intensive luminophore.
