Industrial Test Systems SenSafe 481126 Free Chlorine Test Strip, 40 Seconds Test Time, 0-6ppm Range (Pack of 30)

Works great when used correctly! I did not read thoroughly the 1st time around and my results were off. Second time I was sure to adjust the dip time dependent on the temperature. Very easy to use, and results are fast! Will buy again!

Used these for our Pelican water system to "dial" in the chlorine.

Expire in 9 months.

Easy to use just make sure to read all the instructions. Confirm your water temperature is 75 degrees F. If it’s warmer as mine was 79F, I had to adjust the dip time to 18 seconds. I used these to dial in my Pelican Water WF6 whole house water treatment system. It’s the same ones that they provide with the original purchase.

This was an unwelcome surprise. We just got these today from Amazon and not from a marketplace seller. The expiration date is 5/22. . . just 46 days left on the test strips. Buy a different brand that you can use a little longer. If I hear anything from Amazon or SenSafe, I will update my review. Avoid unless you will use a whole box in 46 days!

This product dose not work do not order this I used several strip that should have tested for chlorine my city water test that is has no chlorine in it at all and I know that is dose you can smell it. do not buy this product also the shipping is terrible took over a month to get it very disappointment.
