The Cyanuric Acid (Stabilizer) test kit measures Cyanuric Acid levels at 20, 30, 40, 50, 60, 80 and 100 ppm. The kit includes 50 Cyanuric Acid visual grade TesTabs® tablets that are added to a test tube. Once the tablet disintegrates then the analyst would look down through the test tube and measure the Cyanuric Acid level by the disappearing dot method.
