Quickly detect the presence of moisture

  • Changes From Blue (low humidity) to Pink (high humidity).

  • Easy to use

  • Great for homes, labs, and science experiments

Our Cobalt Chloride test paper detects the presence of moisture. This test paper is useful in difficult to reach places and recesses. Cobalt chloride test paper is responsive to 50% relative humidity and above, and any direct measure of an aqueous solution.


Place the test strip or sheet near recesses or areas where there may be cracks/leaks.
If moisture is present, the test paper will turn from blue to a light pink/white color.
NOTE: Be sure to keep the strips sealed tightly in the vial, as exposure to 55 percent relative humidity or greater is sufficient enough to cause a slow color change. In addition, if the sheets are heated or the surrounding air dries, the paper will change back to its original blue color.
