The compact high-precision oxygen analyzer SGM5T contains the approved calibration- and drift-free ZIROX zirconia measuring cell as well the electronic unit (for cell heating control, flow monitoring, cell signal processing, calculations and signal output, e.g. oxygen concentration, air factor , redox-quotient or H2O/H2-ratio). A microprocessor changes the cell signal to the oxygen concentration according to the NERNST equation. The value is displayed as an analog current signal (option: digital interface RS232, software for measuring value recording and storage is available). In addition, the electronic unit can process and provide the signals of another, optionally integrable sensor (e.g. CO2-, humidity- or pressure sensor with standard interface).
The oxygen analyzer SGM5S was especially developed for measurements in CO2-atmosphere of breweries. It contains additional parts for gas filtering and pressure reduction.
In the SGM5, the measuring cell is continuously monitored. In case of an error, an alarm signal is generated.
