Bartovation Active Chlorine Bleach Test Strips, 0-2000 Ppm [Vial Of 100 Plastic Strips] Designed For Daycares And Senior Homes For Sanitizing And Disinfecting

They worked as described. This one came in a thicker plastic bottle with plastic sticks too. Good quality! ( I bought another bottle Last week with lower range , 0-400ppm. They didn't work at all. Same brands. The paper sticks are a bit difficult to get them out of the box)

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.

Good
