Most Helpful Review
"A great and more product for measuring chlorine in water. It's digital reading takes out all guessing work and it doesn't require sunlight to be accurate in comparing colors for reading. However, it does consume sacks of additives require for measuring chlorine in water, so my advise is to purchase a good amount of sacks to use them in the test. Also, another recommendation is to carry out this test every a month or so, and use other product strips for quick tests."

Simply easy to use, better than visual color matching.
