Our Cobalt Chloride test paper detects the presence of moisture to determine if you have wetness or dampness problems. The Cobalt Chloride test paper is useful in difficult to reach places and recesses, such as cracks in circuit boards or ceramics. Cobalt chloride test paper is responsive to 50% relative humidity and above, and any direct measure of an aqueous solution. Cobalt Chloride test paper is a fast and easy way to identify leaks in larger spaces, such as roofs, between walls, inside car doors or under ceramic tiles. Larger sheets allow for identification of spray or leak patterns when left in enclosed spaces. Please call for details on special orders as minimum quantities do apply.
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
