Five reasons to switch to optical measurement of dissolved oxygen.

Optical technology saves time and money
Five reasons to switch to optical measurement of dissolved oxygen.
Polarographic sensors often need maintenance.
Reliability and stability from batch to batch is an important condition for the biotech industry. One of the key analytical parameters that can adversely affect the efficiency of fermentation processes is the content of dissolved oxygen. It is usually measured using polarographic sensors. These sensors have been used in the biotech industry for many years. However, they require long-term polarization, and their maintenance takes a lot of time and money.

There is a more efficient way to measure
Optical technology for measuring dissolved oxygen is a minimum of maintenance and high performance. Optical sensors use fluorescence quenching, which accurately and quickly determines the level of dissolved oxygen. Unlike polarographic sensors, optical sensors do not contain electrolyte and do not require polarization. The only sensor component that needs periodic replacement is the oxygen sensitive element.

METTLER TOLEDO complemented this practical design with digital sensor control technology (ISM®), which offers the advantages of advance diagnostics. A dynamic life indicator and adaptive calibration timer inform operators of the need for maintenance. These functions give you confidence that the sensor used will work reliably throughout the entire batch production process.

longer calibration intervals;
high stability of measurement results;
reduced maintenance costs;
the ability to perform calibration at any time and outside the production line.
