2 Pack pH Test Strips, 160 Strips pH.1-14 Universal pH Test Paper Litmus Test Paper pH Soap Making Testing Strips for Water Wine Saliva Urine Soil Testing Pet Food and Diet pH Monitoring (Sealed Pack)

These pH test strips are super easy to use and work just as expected. I’ve been using them for testing my water and plants, and they give clear, accurate results every time. The pack has plenty of strips, so I don’t have to worry about running out anytime soon. Definitely a great purchase if you need something simple and reliable!

Works! A green hot sauce tested pH 1 (red), as it should. Buffered NAD solution tested 5-6. Would recommend

I've used these for testing pH of home made vinegar and our well water. These are the same types of strips I used in College Chemistry. Old Reliable.

I meant to buy the plastic backed pH strips, not the water testing kit. But this did what I wanted. I am planning to use a chemical straightener on hair, specifically Linange Texturizer and Mizani Mild Relaxer. This treatment is alkaline and must be neutralized to a safe p( after the treatment. The strips did a good job of reading a clear pH of 12 for the relaxer, a diluted but still high pH when added to conditioner or oil, and that the neutralizing product has a pH of 6 and does not uniformly or drastically drop the pH as I was hoping it would unless the relaxer is completely diluted.Now that I know what the pH is doing, I can work more safely with the hair treatment. I had hoped to lower the pH from 12 to about 9 to make it milder, but now I know that this does not work with the products that I have. I now know that oil slows the hair straightening process substantially but it does not lower the pH (which makes sense), so now I know that the product is still highly caustic and I will treat it that way. The strips were easy to read. So, additionally, I am not impressed with how well the Linange was neutralized with the Mizani neutralizing conditioner. Perhaps they are the same? But, I plan to use the strips to finally answer the question of whether a different brand works.So, the strips worked out well. I tested the pH before, during, and after mixing and hair strand test experiments. It was fairly easy to determine the approximate pH. Definitely, I could tell a pH 6 from pH 9 from pH 12 - which is exactly what I was after. The tiny droppers were useless to me. Unlike plastic strips where you can grad the plastic part and just not touch the strip, with these paper ones I did need to tear off and prep the strips beforehand so that I would not ruin them before I use them. But, they did work out well. And it gave me the insights needed to work safely with hair treatment chemicals at home.

I use these to test my soaps. They are easy to use!

This test strip came as a yellow strip of paper attached to something similar to a matchbook. I tested several different products as well as my own saliva... They ALL came back same color just wet. DO NOT WASTE YOUR TIME OR MONEY ON THESE

Great value but just not as accurate as a digital ph reader

Love these strips results are very accurate
