| Hanna Part No: HI-93722 Cyanuric acid (CYS) is best known as a stabilizing reagent for chlorine. It is widely applied in swimming pool and spa treatment programs to slow down the decomposition of hydrochloric acid. In outside pool areas, this process is accelerated by the effect of ultraviolet rays. When applied properly, it can save up to 80% of normal chlorine consumption in pools during peak sun months. Cyanuric acid is also used in chlorinated bleaches, selective herbicides and whitening agents. This portable photometer measures cyanuric acid up to 80 mg/L, and thanks to the factory calibration, expresses the reading directly in ppm. The HI-93722 provides the user with much more accuracy than other test kits available in the market at a comparable price. The HI-93722 is supplied complete with 2 cuvets, battery and instructions.
