From Instruments Direct, a pack of individual Chlorine test strips designed for measuring the concentration levels of chlorine in water or a solution. The chlorine test strips are made from potassium Iodide starch paper which allows the easy detection of strong oxidizers like chlorine. These testing strips are easy to use and provide accurate results within a few seconds.
• Take a single testing strip and briefly dip the end into the sample solution or using a pipette place a few drops on the paper itself.
• Remove the test strip from the solution and carefully remove any excess liquid
• Expose the indicator strip to the air
• Compare the test strip with the supplied colour chart
• Full range from 10, 50, 100 and 200 ppm
• The paper will turn from white to blue, to Violette, and darker purple depending on the concentration.
