The "Simple Pack" is an extremely compact water quality testing kit that fits in the palm of your hand (approximately 55mm from the nozzle to the pump) and is lightweight and easy to carry. It requires no specialized knowledge, as the operation involves simply sucking up the water sample and comparing colors. After sucking up the water sample into the container with the reagent and shaking it, the reaction is completed in 10 seconds to a few minutes. 【Features】 ■ Lightweight and compact analysis set ■ No experience or specialized knowledge required for measurement ■ Operation is as simple as sucking up the water sample and shaking it ■ No additional items needed other than this product and the included color chart (excluding COD, NH4, PO4) ■ Easy-to-use individual packaging (mini, Water Check Team series) *For more details, please refer to the PDF document or feel free to contact us.

• Water quality/pH measuring device

The "Residual Chlorine Measuring Device" is a simple measurement method based on the reaction that produces a light reddish-purple color when DPD reagent is added to water containing residual chlorine, depending on the concentration of residual chlorine. The reagent addition operation is performed once. (For total residual chlorine measurement, separately sold potassium iodide is used.) It is an excellent method that clearly distinguishes between free residual chlorine and total residual chlorine. Additionally, the colorimetric plate is removable, making management easy and economical. 【Specifications】 ■ Measurement method: DPD method ■ Produces a light reddish-purple color depending on the residual chlorine concentration ■ Reagent addition operation is performed once ■ An excellent method that clearly distinguishes between free residual chlorine and total residual chlorine ■ The colorimetric plate is removable, making management easy and economical *For more details, please refer to the PDF document or feel free to contact us.
