Description With this Peroxide Check HR water quality testing strip, a high range of concentration can be measured with a single test method. Accurate results from 0 to 30’000 ppm (mg/l) are obtained in under one minute, making the new peroxide test strip ideal for a wide range of industries. Strips are packaged in foil packs labeled with a separate colour chart. This patented water quality test is an attractive alternative to wet chemical peroxide tests for several reasons: Simple Dip-Wait-Read Testing Method Test strips are individually sealed to protect them Ideal for quick and reliable test of water A mechanical reader is NOT required and the unique indicator is reactive only to peroxide. Accurate results are achieved in under one minute. This product is safe and easy to use since there are no chemicals to mix, an MSDS is not required, and the indicator is noncarcinogenic. Hydrogen Peroxide can be used for water desinfection as well as bleaching of hair and other materials. Hydrogen peroxide solutions look like water and can be dissolved in water unrestrainedly. At high concentrations these solutions give off an irritating, acidic smell. Hydrogen peroxide is inflammable. At low temperatures it becomes solid. Hydrogen peroxide is used for different applications, because it is very selective. By changing the reaction conditions (temperature, pH, dose, reaction time and the addition of a catalyser), hydrogen peroxide will attack different pollutions. Suitable for: fresh water samples, including water from taps, wells, springs, boreholes, ponds as well as rain water Contains: 30 individually wrapped test strips Testing Levels: 0, 200, 400, 800, 1600, 2500, 5’000, 10’000, 30’000 ppm (mg/l) Total Test time: approx. 40 sec. How to Use: Dip one strip into a 250ml water sample for 10 seconds. Remove and wait 20 seconds then match to the colour chart. Complete colour matching within 10 seconds. Test uses HRP enzyme with TMB which forms blue in the presence of peroxide. General description: For semi-quantitative determinations. Detection method: colorimetric. Fast, simply dip and read indicator paper. Consists of a plastic strip with attached sealed test paper. Compare colour change of test paper with fields of equal size on colour chart provided on plastic box.
