Used for regular residual chlorine testing in hotel/ryokan hot spring facilities and pools.
Also useful for hygiene management of simple home pools and for checking chlorine removal in home water purifiers.
Recommended for checking when to replace water purifier cartridges.
This is the DPD reagent in tablet form.

*When using in pools or hot springs, the color may briefly turn pink and then immediately become transparent.
This is due to decolorization caused by excessive chlorine. Please try reducing the amount of chlorine and measuring again.

*The color change will also vary depending on the amount of water sampled. If too little water is used, the color may not appear, or if too much water is used, it may decolorize and become transparent.
We recommend sampling the specified amount of water for testing.
