Simplex Health Paper Water pH Test Strips 0-14 Wide Range. High Range Duel Pad for Acid Alkaline Testing (100 Strips)

This pH paper really came in handy. I used it to make home made shampoo and the strips were accurate for what I needed and quick in results. They are multi function and a good item to have around. I liked the little box it came in. Very tidy and easy to store away.

Simple to use, very cheap.

all ok

Did not like them at all. They are all same color, I put each strip into the running tap water, mineral water with electrolytes in it and mineral water without electrolitw, and filtered water and colors havent changed. Same strip colors before testing and same after testing.

Good product

Fast delivery perfect

Delivery good, but strips are hard to determine PH properly and they do run. As soon as you dipped them turn them on their side on a paper down so the run off runs down through its own colour and doesnt mix with the other colours. Had to get an electric pen tester in the end

These strips have worked really well in determining the ph value of home made vinegar after fermentation process is complete.
