Cobalt Chloride test paper detects the presence of moisture from 50% relative humidity and above, and any direct measure of an aqueous solution.
Cobalt Chloride Test Paper
Vial of 100 Test Strips
Shelf Life of 2 Years
INSTRUCTIONS
Place the test strip or sheet near recesses or areas where there may be cracks or leaks.
If moisture is present, the test paper will turn from blue to a light pink or white colour.
ATTENTION! Keep the strips sealed tightly in the vial, as exposure to 55 percent relative humidity or greater is sufficient enough to cause a slow colour change. In addition, if the sheets are heated or the surrounding air dries, the paper will change back to its original blue colour. If the sheets are re-dried, they must be done so with adequate ventilation.
