1. Connect O2 electrode to the BNC connector of a standard O2 meter.
2. Apply voltage of negative 0.8V and record current for various percentages of O2. Then produce a calibration curve for % O2 vs. current recorded on the O2 meter.
3. The calibration curve can be generated by using two known concentrations of O2 standards.
Characteristics:
1. Response Time: About 30 seconds in a well stirred solution.
2. Impedance: Typically, 10 kΩ.
Maintenance:
1. This electrode is prefilled with the O2 solution.
2. If the response time of the electrode increases, remove the luer cap and apply a slight pressure through the luer port. The solution will appear at the vent. Fill the tee fitting with solution provided and close the luer cap.
3. After each use, rinse the tip in distilled water and store wet in the cap provided.
