2 in 1 Water Quality Tester Dual Scale PH and Chlorine Level CL2 Tester Meter for Swimming Pool,Hydroponics, Pools, Spas, Drinking Water Analysis Monitor PH Chlorine Tester Kit

I have only had it for a week. Seems to work well so far. Must be calibrated.

PH meter works, but I cannot get accurate or constant readings - even within minutes I get different readings with a 0.2 to 0.4 difference.Chlorine tester is a total failure. I couldn't even calibrate it - the A to E leters were off by half a turn of the wheel, so I had to mark the wheel to the right position and even so it fails.It is easy to use and a great idea, but it fails to do its job, so for me is a piece of junk.

I use it to test the Chlorine levels in a brine tank, which is part of my manganese/iron removal system. It's a bit of an overkill, but it works well, and I am satisfied with it.

It works great!

Would only measure PH. Would not measure Chorine level at all.

Not worth a flip! It tests ph well but does not test chlorine. On the manufacturer’s website it states that it is already calibrated but it is not. The website does list that you can buy a chlorine kit to make a mixture to calibrate for chlorine but you basically mark where the needle is at that mixture. With my chlorine at optimum levels based on test strips, I still cannot get it to dial in correctly.

MAYBE better with a pool application but for testing lower amounts of chlorine it was too finicky and inconsistent.

Convenient product. Simple to use
