Micro Essential Lab M-1313 Plastic Hydrion Mikro Insta-Check Total pH Test Paper Dispenser, 0 - 13.0 pH, Double Roll

I needed this for a science fair project that got started a little late. I got this quickly with PRIME and it was exactly what I needed. I got some locally that only measured base but not acidity, this has a larger scale and is very easy to read.

Hate it ! It came with one roll which had multiple colors as I opened it ! How in the world will I judge the ph based on color change when the original color is all messed up!? Defective piece

Like the sturdy box these tapes come in. The tape is hard for large man finger to tare off. Using to measure Ph in water to tan fur.

I live in a special hell designed for color-blind aquarists. Doing a basic pH test requires help. These strips are are calibrated to only integer pH values and I find them easy to read. I may only know if I am closer to 7 than 9 but for me, that is progress.

These worked great for us. No problem. We only needed from 3 to 9 and it read accurately. We made 100 readings and still have tape left.

This is a full-scale reading, unlike some other strips that stop at 8 or 9ph. It goes up to 14, so you can see both ends of the scale if you happen to want to know exactly what the number is if it is clearly above 9.I tested these in water, fruit juice and a few other things and the readings were fast and reliable. Some ph strips have reviews criticizing them for turning the same color no matter what, but these weren't like that. Fruit juice came out on the very low side, water came out in the middle, and even a bit left out overnight turned a color.I recommend these.

Good product, 2 rolls of test paper per package. Works well for your PH critical work, whether in foods or aquariums.

I needed a compact flexible and findable when I need it way to test ph. This tidy, water resistant. compact, and accurate kit is perfect for my needs
