Features

• A simple measurement method based on a reaction that reacts specifically when DPD reagent is added to water containing residual chlorine, and then shows a light red-purple color dep***ing on the amount of residual chlorine.
• Reagent addition is performed once (in the case of total residual chlorine measurement, the optional potassium iodide is ***d twice).
• A measuring instrument that can distinguish between free and total residual chlorine.
• Comes in a portable vinyl case.
• You can perform a stability test using a standard colorimetric plate.
• It can easily measure residual chlorine in drinking water and swimming pool water, which is ***ful for sanitation management.
• The colorimetric plate can be removed to remove dirt, cloudiness, etc., and can also be replaced.
• The total residual chlorine can be measured using potassium iodide reagent (sold separately), and the combined residual chlorine concentration can be determined from the difference between the total residual chlorine concentration and the free residual chlorine.
• Application: For water quality control such as tap water, swimming pools, public baths and dialysis water (total residual chlorine).
• * * It may not be possible to measure the test water which contains many interfering substances such as hot spring water and sea water.
