Chlorine Test Paper Strips

We use these in our business and they are easy to use and accurate. They come with so many in the container and you have to be delicate with them. DO NOT OPEN THE CONTAINER NEAR WATER. I know that sounds ridiculous but it happens and they will all be ruined even with a little drop. They accurately measure and you get more than enough to experiment with. I was able to test our water and experiment with them and we still have the same container. They are tiny and stick together so I use tweezers and it's a breeze.

These test strips worked great for making sure I got enough chlorine in my pipes to make sure the coliform bacteria would be killed. It was a little tough when flushing the chlorine out to tell if there was no chlorine or just very little but that's not the fault of these. I just used test strips meant for under 10 ppm for making sure it was clear of chlorine when I was done.

Great Quality

Just ever time nor easy open the container, a little too tight. Easy to use and compare the different colors.

In this current Covid-19 world, I bought a machine to make Hypochlorous Acid (HOCI) as an effective and safe disinfectant. However the few test strips that came it came with had no color chart reference and I wanted to make sure that the machine created the potency that it claimed, so bought these strips. Pros: - decent size test strips - color chart included directly on each bottle (4 potency level: 10ppm, 50ppm, 100ppm, 200ppm) - machine makes 3 different potencies and the test strips were easy to use (I used 3 different test strips per potency to compare to make sure) - decent price for the amount that you get Cons: - none for me :)

I have jugs of chlorine bleach that have been open for awhile, and I wanted to check their potency. When I dipped the Bartovation test strip into the chlorine, the area where the strip was submerged turned white and the edge of the saturated area changed color. Another reviewer had mentioned this happening, and I feared I’d received a similar “bad batch”. I then reread the instructions which clearly state the strips are *not* to be used in undiluted bleach! (There’s nothing like reading the instructions, Grasshopper.) So I tried again, this time with a diluted bleach solution, and voila! Perfection. Here’s the entire fine print about what solutions will and will not work with these strips: IMPORTANT NOTE: This strip was designed specifically for restaurants to test chlorine sanitizers in three part sinks. It will work for testing anything in the range of 10-200 PPM. IT WILL NOT work for testing tap water, pool water, undiluted bleach, or anything that uses Quaternary Ammonia as the active ingredient.

It was just what I needed and was of great value

The took a few tries to get used to them....I originally though that they would be a little thicker like my pool test kit. but they are really thin paper and the vile is small. BUT I need to bleach my well water and components to my well and test a lot of water lines in the house. These strips worked great in order to see if I had enough bleach in the system. Please note: These test strips test from 10-200 PPM of Chlorine. So I needed a different strip to ensure that there was no residual Bleach in my well.

I like this chlorine test paper and repeated my purchases. But my order is for 1 items of 10 vials at S$120.64, only 1 vial was delivered on 26.7.2022

Very good and accurate product, will recomend and will purchase again.

excellent product and seller

I received my order today, and the test strips must be old because they do not work. Very disappointed.. How do I return them?

Muy bien un poquito finas pero están bien
