Industrial Test Systems 480010 SenSafe Total Chlorine Test

I bought this along with the free chlorine test kit to monitor my well water treatment system. It does work OK if you follow the directions carefully. I use these for quick week checks. I needed more precise results while I dialed in my chemical injector so I ultimately bought a more expensive test kit from Hach, but still use these to verify nothing's gone awry.

Works just fine for me.

Very Inaccurate. Super Cheap. Total waste of your money. You will at best just hurt your machinery. At worst you might hurt yourself or someone else.

I got these to help determine whether water appearing in my lane is leaking mains water. I tested the water coming out of the kitchen tap first but got a zero result. The water does actually smell slightly of chlorine, and our local environmental health person has confirmed that there is chlorine in it. So I can't even detect chlorine in what I know is chlorinated mains water. Therefore this is not fit for my purpose.

The colour guide when testing is in sheds of green to show the levels but isn't very clear at all as the shade on the strip matched about four different levels

The colour change strip is very hard to compare to the colour chart to get an accurate reading. If you are looking for the presence of chlorine they are ok, but to get a percentage of chlorine in a sample can be hit and miss unfortunately.

These strips are perfect! I need to know how much chlorine is in my water tanks without the rhubarb of meters and calibration. And these strips come with regulatory authority approval which we need.Work like a charm and easy to use for non water testing professionals.
