Plastic pH Test Strips, Universal Application (pH 4.5-9.0), 100 Strips | for Urine, Saliva, Aquariums, etc.

I use this product as an affordable quick check of the pH for the nutrient water I use for my garden, greenhouse, hydroponic and aquaponic systems. Although I have a "proper" pH meter, maintaining the electrode is a hassle for this purpose, and honestly, its accuracy is overkill.The pH detection range of these strips is ideal for growing plants since most plants respond best to a pH of between 5.5 and 7.

I am a retired industrial chemist and have used just about every type of pH measurement devise there is and usually stay away from test strips. While the strips will give you an approximate range of pH value, it is often hard to determine a specific value. With these strips the indicator colors are easy the use and each pair of colors is clearly specific to a specific pH value. Great tool!

Using another test strip and API chemical test methods I get a pH between 7.4 and 7.6. These strips constantly read 6.5. They look nice in the trash bin.

Easy to read. Good fair gradients. easy to handle. Consistent results, check with other doctor office product. All in all, a good product at a fair price. Fast delivery.

These are the best imo, the plastic container that the sticks are contained in has a graph, or color chart that goes all the way down to 4.5, the others that I have ordered only go to 6.5, use them for my dogs because the P.H. reading has a lot to do with whether or not they may have a urinary infection or something going on with the kidneys. Very good product.

I use two different brands of pool test strips for a number of pool chemistry parameters. The both work pretty well except for pH. I don't really understand why but they both diverge by a significant margin. These pH strips are great - easy to read, and hopefully, right on the money.They must be working properly because my pool is perfect!!

These work pretty well as long as you don't let the color from one patch bleed into the adjacent patch. The strips were all jumbled up in the case when they arrived. It didn't seem like it could be just shifting during shipping, but more like they had been dropped and then stuffed back into the case.
