Hanna Instruments HI96722 Cyanuric Acid Portable Photometer with Sample Cuvettes, 7-19/32" Length x 4-3/32" Width x 2-11/16" Height, 0 - 80mg/L, 1mg/L Resolution, 9V Battery

The HI96722 meter measures the cyanuric acid content in water samples in the 0 - 80 milligrams per liter (ppm) range. This meter uses an exclusive positive-locking system to ensure that the cuvette is in the same position every time it is placed into the measurement cell. It is designed to fit cuvettes with a larger neck making it easier to add both sample and reagents. The cuvettes are made from special optical glass to obtain best results. Cyanuric acid (CYA) 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 hypochlorous acid. In outside pool areas, this process is accelerated by the effects of UV rays. When applied properly it can save up to 80 percent of normal chlorine consumption in pools during peak months. Cyanuric acid is also used in chlorinated beaches, selective herbicides and whitening agents. HI96722 is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. 1 milligrams per liter resolution. +/-1 milligrams per liter +/-15 percent of reading at 25 degree C accuracy.
