Oops, I just noticed that I may have misquoted the price. I believe they are $8.30, and I think I said they were $8.33. I will have to go back and see if that is what I posted.
Yep, I listed the wrong price. Oh well, I hope people won't be put off by the inflated cost. You now won't have to bend over to pick up those last 3 pennies off of the ground...
For the record, the listed cost at Cole Parmer is $8.30 + shipping.
These test strips are also available from other sources. I went with Cole Parmer because I have an account there.
Yes, the ones you found are the same thing. For our purposes, the 0 - 10 ppm ClO2 strips should work fine. I see they run $11.44 from Sanitation Tools. The picture they list is exactly what I got from Cole Parmer.
