Quaternary ammonium test paper roll type with dispenser 0-400 QT-10 1 roll/each

Used to measure the concentration of disinfectants containing quaternary ammonium. Dip the test strip into the sample disinfectant solution, leave it there for about 10 seconds, then compare it with the color chart to read the ppm value. Since the launch of Micro Essential Laboratories (MEL) in 1934, MEL has gained experience with the dyes it uses and has made efforts to expand the range of uses for pH measurement, resulting in the establishment of the Hydrion brand. Today, MEL's quality, accuracy, and reliability have set the standard for quality. For unknown samples, we recommend measuring the pH value beforehand to be on the safe side. In the food industry, for example, it is essential to check the chlorine concentration required for disinfection. This is a roll type that allows you to freely decide the length of the test paper. ppm measurement range: 0 to 400 Size: 5.5mm x 4.57m Roll type with dispenser Quantity: 1 roll *If the sample is expected to be a strong acid, please use it with due consideration to safety.
