The Extra High Level Peroxide test strip is calibrated at 0, 500, 1000, 2500, and 5000ppm, and gives results in 90 seconds. THIS TEST IS NOT FOR TESTING DRINKING WATER OR HOT TUBS! These strips are used to test concentration levels of Peroxide solutions used in cases where strong disinfection is needed. This test strip is designed to work with solutions prepared from concentrated hydrogen peroxide only, including hydroperoxides and ether peroxides. It should not be used to test solutions made using “accelerated” hydrogen peroxide products as they require a special color chart. Instructions: Remove one test strip from the vial. Do not touch the test pad with your fingers. Dip the test strip into the solution being tested for 1 second. Remove and do not shake the strip & compare the test pad to the color chart after 90 seconds.
