Kombucha & Fermentation pH Test Strips – Instant Read pH Strips Dispenser for Brewing & Fermentation, pH Range 0–6

They work great. Easy to use and a great value.

Very accurate. Good quality for the money.

These strips were way thinner than I thought they’d be but despite their flimsy feel, they did the job. Somewhat hard to separate one out and I had to take care not to contaminate the lot. Easy to read the pH with the scale on the box. You get a lot of them so I didn’t mind testing often. Size was ok for me and worked fast to give results. I have had them several months and they still read well. Just need to take care not to get them wet and seal them promptly after use. All in all, they did the job well and I would buy them again as they were a good deal.

Have not checked it's accuracy but seems works well for my applications.

These ph test strips work great for canning. Only wish the case was made a little different so they dont get caught when closing the container.

I’ve made 7 batches so far it’s great

I bought these to test the pH of activated EM-1 (microbial soil inoculant). As a check for accuracy I also tested the pH of lemon juice (albeit a little bit old, and not fresh, unfortunately) and of white vinegar, both of which were about what I'd expected. When I tested the EM-1 solution the strips indicated a pH of about 3.7, which is right in the range I needed. My only beef is that, while the hard plastic holder for the pH strips is awesome, the fit between the bottom and the lid is hella snug. As a result, when I finally got the lid off all of the pH strips were launched onto the floor even though I'd expected and tried to prevent it. Fortunately, the floor was dry. Unfortunately, all of the strips were exposed to the humid summer air, so who knows how well they'll keep. Plus, it took forever to get them back into the holder. Like, have you ever tried to fill one of those plastic q-tip travel containers, or maybe one of those round bathroom q-tip holders, with fresh q-tips? It takes forever thanks to the recalcitrant q-tips that want to go in sideways and block the rest. It was like that, only with flimsy strips of plastic that can't just be shoved. Yeah, I should've just put them in a freezer baggie, squeezed out all of the air, and called it a day. ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯ Bottom line: I'm happy with these strips. They aren't perfect but their accuracy is close enough for my needs, especially for the price.

I tend to make a lot of small batches of mead. Those who make mead know that PH tends to be something you need to be a little cognizant of. These strips are fast, convenient, and with the east to read chart on the back of the container, makes knowing exactly where your brew stands easy and simple. I've had a few brews stall due to low pH, and these strips have allowed me to bring them back from the brink of throwing them away. If you're brewing and not keeping track of your ph, it's something you should do. Make the investment in your hobby and pick up a pack of these.

Happy with these, new to fermenting and they certainly helped.

I have bought these before and was happy it was still available. Very easy to use and read the results. I use them to test my ferments before eating them. I find they are accurate. Good value for my money cause it takes the guess work out of a spoiled or not spoiled ferment.

Works like a charm

I just discovered these and they take the guesswork out of ferments. Very helpful after you get used to reading the colors. Although the top doesn't display for me exactly the same as they are matched on the back diagram, I tried them on known acidic and alkaline substances, and that took the guesswork out of reading the strips. It is very obvious and easy to match after a few tries. I really like the packaging. Will buy again.

Works just as expected. I wish I had not purchased the digital devices as these work just as well for what I need. Good ‘in your face’ readout.
