Best pH Test Strips of 2025

"I found these to be good quality and easy to use. They provide quick results and are actually fun to test things with!"

"I bought these to test the pH level of my hydroponic garden. Unfortunately, they only work at high concentrations, and I was hoping for better results. I noticed that they work with coffee, but for my plants, they just didn’t provide the level of indication I needed."

"I received my three packs of litmus papers promptly, but I was disappointed to find that there was no storage box included. Overall, they are exactly as described and I'm happy with my purchase."

“I appreciate how easy to use these pH strips are. The results come in just 30 seconds, which is incredibly convenient for my aquarium.”

“While I like these strips, I do wish they had a longer shelf life than 90 days. It would make a big difference for my projects.”

The strips consistently provided accurate results and the color changes were clear and matched well with the provided pH chart. I appreciated the versatility of these strips for testing various substances, making them a valuable tool for my needs."

"While they do work, I found these strips to be not my first choice. The strips tend to fall apart and aren't as user-friendly as other brands I've tried. I wanted to test if my leaking fluid was amniotic fluid or urine, but I needed a significant amount of liquid for them to register. However, they did change colors when tested with other substances, so I guess I'm not leaking amniotic fluid. Just wish they were more fortified like other options."

"I make kombucha and wanted to improve its quality. These strips offer great value and perform well for my needs. They're accurate and easy to read, with distinguishable colors. I've even compared their readings with lemon juice and found them reliable. Plus, they last a long time!"

"I had been feeling REALLY UNWELL for months. After changing my water consumption and diet, I saw immediate results. My heartburn decreased, joint pain is nearly gone, and I haven’t experienced nausea or vomiting. I feel like my old self again!"

"This product served its purpose well, allowing me to observe my pH levels effectively. It helped me understand my body's responses to what I eat and drink."

"I struggled with bladder problems and was facing surgery. Using these strips, I monitored my acid levels and changed my diet. Now, my stream is great, and I canceled the surgery!"

"I find this item great because women need to understand their pH levels. The instructions are clear and simple, making it easy to use. I've noticed that the reading is immediate, yet I still wait the recommended 20 seconds for results. I absolutely recommend this to every woman!"

"These strips worked perfectly for me. They look just like the image and are comparable to any good brand I've used."

"Although I’m not entirely sure if they work accurately, I really appreciate the concept behind these strips. They are very convenient for quick testing when something feels off. I would suggest doing a bit of research before buying to ensure their accuracy."

"I've tested these strips against a pH meter, and they proved to be really accurate, fast, and easy to use. I can get results close to the nearest 0.5 pH."

"Having an electronic pH tester was effective, but I felt uneasy using it with flammable liquids. I decided to try these strips and found them to be pretty close to accurate, especially when precision isn't critical. They can be a bit tricky to read if the colors are ambiguous, but I would buy them again once I run out."

"After using these pH test strips for several months, I am thoroughly impressed with their accuracy. They come in a convenient package, making them easy to store and access. The instructions are straightforward, and the results are simple to interpret. I've tested various solutions, and they consistently deliver reliable results.

“I've had issues with the color matching on the pH strips. It’s good for a guestimate, but I wish I felt more confident in the results.”

“As someone who's dealt with kidney stones for years, I really appreciate the value of these strips. They arrived quickly, and I’m glad to be able to test my urinary pH regularly.”

"I found the instructions clear and the process simple. I got these strips for basic pH testing in my hot tub, pool, and drinking water. They work well for that purpose, but I still use other strips when I need more detailed information."

"Using these strips was a breeze! I tested the pH level in my drinking water, and the color accuracy was identical to the chart provided. It was a straightforward process, and I would definitely recommend them."

"I ordered these strips for a homeschool science lab to test the pH of various substances. They are perfect for our experiments, and I love that we have enough to repeat tests as needed. They're also great for checking our pool and hot tub water!"

"I’ve tested these strips on tap water, ZeroWater, and concentrated vinegar. Based on the pH levels I found online, they seem to be accurate. They are definitely easier to read than single color litmus paper. I can differentiate pH levels to within 0.5, which is perfect for my carnivorous plants that thrive at a pH between 4.5 and 5.5. I believe many complaints stem from people ordering the wrong type for their needs. There are two types: one for 0-14 pH for all liquids, and another for saliva and urine. Make sure to order the correct one!"

"I've used many pH strips, typically the expensive German brands because of their accuracy, but these are the best I’ve come across for the pH range 4-9 or 0-14. I will definitely be purchasing more of these!"
