The ADOS TOX 592 gas sensor is suitable for continuous measurement of a concentration of toxic gas in air over the range of 0 - 20 ppm to 0 - 1000 ppm. The ADOS 592 CO gas sensor uses a method of measurement where the air to be measured is diffused in a chemical measuring cell.

The (H+)-ions and the electrons released are consumed at the electrode in a cathode reaction.

The flow of current between anode and cathode generated by this process is directly proportional to the CO-concentration in the measured air.

The sensor current is amplified and applied via a 4-20 mA interface or via the LON® field-bus to an evaluation unit e.g. ADOS Multitronik 592 where the measured variable is processed and indicated in ppm CO together with any control and warning functions which may be necessary.
