What is a digital dissolved oxygen sensor?

A digital dissolved oxygen sensor an in-line analytical instrument designed for continuous DO monitoring and control with real-time results, for a range of industrial processes. METTLER TOLEDO's digital dissolved oxygen sensors use a technology called Intelligent Sensor Management (ISM). ISM dissolved oxygen sensors offer a strong digital signal to prevent signal interference, so you can place your dissolved oxygen analyzer wherever you need it. They offer predictive diagnostics that clearly show in days when your ISM DO sensor will need replacement parts or calibration. 

How does a digital DO oxygen sensor work?

Digital dissolved oxygen analyzers work based on the technology of the METTLER TOLEDO DO sensor selected. METTLER TOLEDO offers two digital DO sensor technologies: Amperometric and Optical.                                                                                  

Amperometric: These in-line dissolved oxygen sensors use a gas-permeable membrane to separate the sample from an electrochemical cell in the sensor. Oxygen diffuses through the membrane in direct proportion to the partial pressure of oxygen in the liquid outside the in-line DO sensor. A cathode and anode inside the probe are polarized with a voltage to enable the electrochemical reaction of oxygen. Oxygen is reduced at the cathode while the anode is oxidized, producing a small current in direct proportion to the amount of oxygen in the sample. In addition, the dissolved oxygen sensor uses the temperature value to convert the oxygen partial pressure signal to a dissolved oxygen concentration value by compensating for the changing solubility of oxygen with temperature. 

Optical: These in-line dissolved oxygen probes use optical technology for measurement. They contain an oxygen-sensitive layer that can fluoresce. This layer absorbs light from a light emitting diode in the sensor, and the light is released as fluorescence. The fluorescence lifetime depends on the amount of oxygen present in the sample medium.

How do you calibrate ISM digital dissolved oxygen sensors?

ISM dissolved oxygen sensors store their own calibration data, so they can be quickly and accurately calibrated in any convenient location without having to adjust the transmitter. To increase productivity, ISM technology also provides accurate diagnostic tools to notify you when your sensor needs calibrated. Calibration processes vary based on the technology and type of sensor, but all digital dissolved oxygen sensors can be calibrated on-site by trained technicians.
