Ionrich hydrogen water testing kits come with hydrogen water reagents testing drops and chlorine residual reagent testing drops. This is an essential testing tool for accurately measuring dissolved hydrogen concentration and purity level without mixing of chlorine residual in hydrogen rich water. In these Ionrich hydrogen water testing kits, both reagents are included in a 10 ml - 10 ml bottle. By using hydrogen reagents and testing drops, you can check the accurate concentration of hydrogen H2 in water. Japanese researchers found that methylene blue colloidal platinum drops can be used to determine hydrogen concentration accurately. Although hydrogen testing meters also come on the market, but these meters can't show accurate readings, and hydrogen meter calibrations are very sensitive to dust so once its calibration damage it can't be repairable and shows you an accurate reading of hydrogen concentration. Further to create awareness about the purity level of hydrogen water we give chlorine residual reagents in this kit. As many people are unaware that some hydrogen water bottles claims SPE-PEM technology (Solid Poly Electrolyte Proton exchange membrane) hydrogen water bottles, but there poor quality membrane cant stops chlorine residual and ozone residual to mix in hydrogen rich water hence these cheap type hydrogen water bottles generate chlorine and other residual gases along with hydrogen. When you use a chlorine residual testing kit and put chlorine reagent drops in the hydrogen water, the color will be yellow, which means chlorine residuals are present in hydrogen water. This is why we always recommend you to use only hydrogen water bottles from SPE-PEM technology. As a result of research and testing, Ionrich Hydrogen Water Testing Kit is now available in the market. This kit is for the purpose of testing purity and quality of hydrogen concentration levels of hydrogen rich water produced by hydrogen water bottles.
