Hydrion pH Strips ph range 1-12 100 strips per vial

Love these, super cheap, easy to use, and accurate. We are gender swaying and using them to test cervical mucous and semen ph, and didn't want to spend a ton for full range ph test strips as we will go through quite a few. I tested milk, vinegar, and several other known liquids to first "test" them, and all were accurate.

Not much to say, they are PH strips, and they work as advertised.

These strips do exactly what they say they will do and are a bargain compared to most. We just started making Kombucha and needed pH strips to test acidity. The range is perfect for this application, the strips work quickly and are accurate. The color guide on the side of the container is also accurate. Good product, good value, delivered on time and in good condition.

It really depends on what you want to use these for. If you want to ballpark a pH these are great and appear to be accurate. I bought these to test some cosmetic formulas I’m developing at home after two of my pH meters broke. I tested my new facial cleanser, tap water, and an glycolic acid, and they all tested at about what they should. In terms of accuracy, I’d still go with a meter over strips, but if you want a quick confirmation of your gut, these are fine. I’m a designer by trade, and it can be tricky for me to decode the colors.

I have used different PH strips similar to this design in the past. Was very disappointed to find strips stuck together like a roll of paper towels, which required pulling one off at a time. I could of overlooked that part. Not so much for the false readings. Several different individuals tried it, which all resulted inthe same way, ended with a wet strip with no color change at all. I bought these strips due to the fact, they were made by a Lab company in the USA. This company surely has better quality work, instead of passing off merchandise that's out dated. I would of given 0 stars if I could.

These are the ones pros use, to my knowledge. I don't have any way to accurately test if these are calibrated perfectly, but they can give you insight as to whether that batch of ferment is better thrown out or safe to eat.Some of the color transitions are a little difficult to compare to the included chart.

I've been using these strips to test the pH of my dog's urine to prevent the reoccurrence of bladder stones and due to the fluctuation of readings I have been getting I couldn't figure out if they were accurate or if I was not using them properly. I tested a lemon which read around 2, and milk which read around 7, so they're definitely not off. I will probably get some strips that measure to .5 accuracy, but these do work for a quick read. I like that they give a very instant read so I don't have to collect his urine in a dish and let the strip sit there for 10 seconds- i know that's weird but it is what it is

If you are looking for precision this item is definitely not for you. The strips are rather thin (less than 1cm wide). Colours 1-2, 4-5, 10-11 are virtually the same and so it is very hard to read the PH accurately. Furthermore, I got mine to make stretched cheese for which acid development is important, yet every reading I get from milk or whey seems to stay in 6.
