Oxygen measurement with optical technology uses a mechanism called fluorescence quenching. Instead of measuring current it detects changes in the time scale of the fluorescence signal. The fluorescence lifetime is directly correlated to the oxygen level in the sample.
This technology offers more simplified maintenance as the absence of electrolyte and membrane body means maintenance is easy and needs no specialist know-how.
Together with Mettler Toledo’s Intelligent Sensor Technology (ISM), optical oxygen technology provides outstanding sensor reliability and process safety. Online diagnostics inform the user about the wear on the sensor and the need for maintenance - making the decision to use a sensor for the next batch easier.
In addition, with iSense Asset Suite software, calibration and documentation of all actions during the sensor lifetime can be recorded electronically.
