Optical Dissolved Oxygen Sensors

METTLER TOLEDO optical dissolved oxygen sensors offer highly accurate O₂ measurement with enhanced signal stability and fast response time. Measurement accuracy is achieved through fluorescence quenching technology, which is the result of an energy transfer between a fluorescing chromophore and oxygen molecules. As fluorescence quenching does not require polarization, optical sensors are available for measurement immediately and help you focus on the most important thing – the process itself.

The OptoCap sensing element on the optical dissolved oxygen sensors provides highly accurate oxygen determination and easy maintenance, without time-consuming electrolyte handling. It prevents bubble formation on the sensor, eliminates noise on the measurement signal, and leads to stable and reliable oxygen measurement. OptoCap was designed and developed by METTLER TOLEDO and has become the standard for quality throughout the industry.

The METTLER TOLEDO optical dissolved oxygen sensors offer incomparable flexibility and ease of handling. Plug and Measure in the optical dissolved oxygen sensors leads to faster start up, no configuration is necessary and the risk of handling errors is eliminated. They are compatible with digital and analog installations, sterilizable, autoclavable, and fulfill industrial requirements for hygienic design and traceability.

Thanks to Intelligent Sensor Management (ISM) technology, real-time sensor diagnostics provide all necessary information for deciding if a sensor is good for the next batch. Predictive maintenance tools for pre-batch diagnostics, support production planning and avoid outages during production. The optical dissolved oxygen sensors are designed for analog or digital environments. Analog installations can be upgraded to digital without additional investment in new peripherals.
