We will launch the "Pack Test Total Hardness (Low Concentration)" on June 3, 2024. This product can measure total hardness, which combines calcium hardness and magnesium hardness. Please use it for water quality management of water softeners, pure water production systems, and boiler water supply management (below 1 mg/L).

We will start selling the "Pack Test TOC" from September 1, 2023. This product is a screening kit that allows for easy measurement of the approximate value of TOC (Total Organic Carbon) in water using a pack test. The measurement principle employs the potassium permanganate colorimetric method to estimate TOC. (Measurement scale: 0, 3, 5, 8, 10, 25, 50 mg/L) The main applications include management of drinking water, industrial water, and bath water. *Samples will be available from late August. Please contact us directly if you need them (details will be announced later).
