This measuring instrument is a simple measurement method based on the reaction of pale red purple, as in the "residual chlorine measuring instrument DPD method", the residual chlorine and DPD reagent contained in the water test reacting and the pale red purple color. By using a dedicated medium concentration ratio plate, the concentration of 2.0 to 10 mg/L can be measured in 6 steps.

The measurement of the residual chlorine can be measured using a DPD reagent, and then the potassium reagent reagent can be performed to measure the total residual chlorine. From the difference between the residual chlorine concentration and the residual remaining chlorine, the binding residual chlorine concentration such as monochloramine can be obtained.

【feature】

・ By using a DPD reagent or potassium pigedix, you can measure 2.0 to 10 mg/L residual chlorine concentration (free residual chlorine, binding remaining chlorine, total residual chlorine).

・ If you have the main unit of the remaining chlorine measuring instrument DPD method, you can use the same operation method by purchasing only the medium -concentration ratio plate and replacing it.

-The reagent used (DPD reagent, potassium porcupone reagent) is the same as the "residual chlorine measuring instrument DPD method".

・ In order to avoid increasing the number of Legionella belongings, which causes Legionellasa, which is classified as a class, it is necessary to manage facilities and equipment on a daily basis. Therefore, this product is useful for managing the residual chlorine concentration used for disinfection.
