Product details for O2 Test Kit
Full product description
Test kit for spa or pool.
pH and active oxygen analysis with tablets.
The oxygen content should be at least 8mg/L between 1 and 2 hours after the care product has been added. It is not possible to make an accurate measurement at a later time because it is then no longer possible to show the oxygen content.
pH values below 6.8 also produce a yellow colouration, so a reading 6.8 may be incorrect.
pH values above 8.2 also produce red colouration, so a reading of 8.2 may be incorrect.
Incorrect measurements are possible where very soft water is involved.
