JOHNSON UNIVERSAL pH INDICATOR STRIPS 0-14 NON BLEED

The sticks themselves are good but unfortunately the bar code sticker was placed right over the plastic box meaning that you cannot easily read the chart without removing it so it makes it difficult to use

it did what it was required to do

so so

These test strips are very easy to use and come with instructions. Its definitely good value for money as there are a lot of strips inside. I used them to test the ph balance in my hair products.

Tried to use these for a fish tank PH tester, nothing changed on the paper so I put vinegar on it to test and again. no change. Maybe I did something wrong but I read what to do and nothing happened.

just received this strip , fast service :) would buy it again :)

The Johnson strips read out on the low side. To get a more accurate reading I have to leave the strip to soak up the sample for a minute or two instead of the 40 second advice time given on the box. I base my comment on having used Phion strips previously and on a liquid test solution I used in the past. Our tap water is 7.5 but these strips read at about 6 unless left to soak for a few minutes when they do read close enough.
