FAQ

How should I store my polarographic DO sensor?

For short term storage (< 1 month), polarographic DO sensors should be stored wet in electrolyte solution with the membrane immersed in a watering cap. For long term storage (> 1 month), remove internal electrolyte, rinse cathode and membrane in deionized water, and store dry.
