Ammonia solution concentrated
Concentrated ammonia solution (25 % - 30 % ammonium hydroxide solution, ammonia) is used for the service of the polarographic oxygen sensor OroboPOS. After opening the commercial solution, the concentration of ammonia may decline during storage and may render the ammonia stock ineffective for sensor service.
Source: A commercially available solution from a drugstore is sufficient for this cleaning purpose
