Insta-Test 5 Way Chlorine/Bromine test strips are accurate and reliable. With instant-read, you can have results in seconds. Measures Free Chlorine / Bromine, Total Chlorine, Alkalinity, pH and Total Hardness.
Instructions for Use
It is important to carefully read the instructions on the test strip bottle for proper use. There are several tips that will help you consistently obtain accurate results. For example, the reason that the instruction says to read the strip starting with chlorine at the top is because the pH and hardness pads need about 10-15 seconds to fully develop; by the time the strip is removed from the water and the initial three test factors are carefully read, the colors for pH and hardness are ready for evaluation.
Note: A color that appears on the test strip may be between two color chart values. If this happens, record the result as a number in between the values shown.
Note: The magenta (hot pink) values represent bromine test results and are found just below the free chlorine values printed in black.
