Bartovation Cobalt Chloride Moisture and Humidity Detection Test Paper [Vial of 100 Strips]

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. Instructions: Place the test strip 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.
