HYDRION pH 15 Foot Roll with Chart and Dispenser 5.5-8.0 pH Range

Great pH paper for working in the neutral range of pH. Easy to use, a fair amount of test paper for the money (~150 or so tests if using 1.2 inch strips), easy to read based on how dark the paper is (so probably fairly easy to use even with colorblindness), and results are consistent with a digital pH meter.

I use this when canning tomato's and other things to know when to adjust the acidity of the product before canning in jars. This is more accurate than just guessing.

Works well

This pH tape is accurate but the dispenser is a little awkward to use. The paper does not tear off easily.

Great for what I need it for! - I use these to test my dogs urine actually. She has a history of bladder stones and using these strips helps me keep her urine at a lower (correct) pH and lets me know when its off!

I’ve been buying these very reliable, easy to use test strips for close to 20 years and check my numbers nearly every day as it helps see what diet does to your alkalinity. I like to be more on the alkaline inside than acidic for many reasons.

Buenísimo ayuda mucho

when you get into the zone you need to be, the colors are so close you cant really identify what it is . The doctors office has one that you can read much more clearly. so only a 3 star for now
