Active Chlorine Bleach Test Strips, 0-2000 ppm [Vial of 100 Plastic Strips] Designed for Daycares and Senior Homes for Sanitizing and Disinfecting

it helped a lot with the disinfection process of the house plumbing, but having to wait for one minute (according to directions) for results, was too long, when three other types that I bought only required 5-10 seconds in one case, and 1 second or less for the other two. It appeared however, that even for the unit I'm reviewing results were accurate enough in much less than one minute, in no more than five seconds in fact. And this unit was the only one to show results for more than 300 PPM. Another remarkable feature was the wide range of color variation, which made it easy to pinpoint the chlorine concentration.

I just started making HOCl (Hypochlorous Acid) for our small business. In order to make it to the correct specifications, I needed a way to measure the strength of the solution so it's not too strong or too weak. I checked out various reviews and decided to buy two tubes of the Bartovision test strips. They were much less inexpensive than I had imagined they would be, and they arrived quickly. When I started using the strips on our solutions, I had technical questions to make sure I was using them correctly, so I contacted the seller via email. Much to my surprise, the owner of the company called me the next day and answered all of my questions. Super nice guy and very helpful. What a wonderful experience especially in this day and age. I would HIGHLY RECOMMEND these test strips to anyone! Richard in Colorado

It was great to know when I needed these strips were available for me to purchase. I used it for testing the water in the classroom to make sure it met state regulations.

Good product.

Quick use for daycare center assessment of bleach solutions to ensure dilution was done and not over diluted as well as not too strong

The price of the product is very expensive, and the cost performance is not high for the commonly used units！

Chlorine bleach solutions are very effective disinfectants at the correct solution concentration. These test strips allowed me to mix the concentration reported to be effective for killing coronavirus. You never know what concentration you actually have when you make solutions using bleach you purchased a while ago because bleach deteriorates with time. I have found that solutions I prepared using the dilution instructions on different bleach bottles gave very different strengths. I can now m using my bleach supplies effectively with no wastage.
