Easy to use product

Easy to use and read. Accurate results. Used to test free chlorine levels in a small community water system. Easier to use than a colorimeter.

I have tested 3 different brands of test strips over a 7 day period and they did not correlate at all.0.2 to 4.0 That is a huge difference when you are drinking the stuff.If you simply need to check if you have chlorine in your water these will work. If you need a definitive number go with a Taylor chlorine kit instead.For reference:I check my drinking water tanks for free chlorine every morning. When it gets below 0.2, I add 2.5 teaspoons of (drinking water approved) chlorine granules to a 2500 gallon tank. For our water usage, it will last a week before I need to chlorinate the tank again.

Totally defective. Produced 0 PPM results repeatedly on water confirmed to contain 2.6-3.0 PPM.

My apartment complex stopped softening the water the chlorine jumped. Good to keep track of chlorine

First time trying this brand but it's a easy to use kit, and the tests are accurate so far.

Just follow the easy instructions and you will get results. The kit inspires customer confidence.

Reads low. We thought these test strips would be nice to use in the field but comparing the same water we have found they consistently read low. The calibrated lab photospectrometer would read 1.2 ppm and the test strip would show around 0.5. They are OK to show the presence of chlorine but don't rely on them to show how much.
