Macherey-Nagel 92110 0-14 pH Indicator Strips 100/Box

These pH test strips are really easy to use. The color chart is clear and accurate, which makes it easy to read the results. They’re quick, mess-free, and reliable. I use them for my homemade products, and they’ve helped me adjust the pH correctly which is essential for skincare and proper preservation. I would definitely buy them again.

I use these strips in conjunction with my PH meter and the strips are always accurate. Obviously I can get a more precise reading with my ph meter, but these strips are handy when I don't need a precise reading.

Works as described.

I have a quite acidic vegetable fertilizer (kept acidic for long term storage) and I wanted to bring it to roughly neutral pH using a potassium hydroxide (KOH) solution I made from powder, and needed to figure out how much KOH to add. As with all pH test strips, these are nothing like a pH meter, but it was easy to figure out how to get things in the neutral range using these strips. I work in a university research lab, and Macherey-Nagel is a good brand. I would pay considerably more buying it from one of the scientific supply houses than the Amazon price so I am happy with what I paid given these are high quality.

Reliable results, does its job well.
