Rapid breathing on the surface of the water is an unmistakable sign of a lack of oxygen, unfortunately it may already be too late to intervene. The sera O 2 -Test detects the actual oxygen content of the water in minutes and enables timely intervention. A rapid increase occurs with sera O 2 plus. Sufficient for approx. 60 measurements.
