Litmus PH Test Strips 160 Strips, Professional Universal pH.1-14 Test Paper with Test Pipette Droppers, for Teaching, Student, Chemistry Experiment, Saliva Urine Water Soil & Diet pH Monitoring

I was about to leave a bad review and ask for my money back when I read another review that made me think about testing other things. I bought these strips to test the PH for my Orchid fertilizer to make sure it was in the right range. The test for that in my tap water both came out yellow looking pretty much like the original paper but after I tested orange juice, Windex , rice vinegar, and a few other things the papers actually worked. If your paper turns yellow rest assured that it’s in the range indicated by the color indication strips.

I does what it does, just se cant tell what ph it is like in scale but colors reveal actual if its acidic, alkaline or neutral.

Although I have the Blue Guardian PH pen, I purchased these PH test strips specifically to use for Kombucha making. I didn't want to cross-contaminate my hydroponics PH pen in my Kombucha SCOBI.The strips arrived quickly and were packaged safely.My kombucha kit came with a kit of test strips that were white and easy to read. These strips were yellow and slightly more difficult to read precise measurements. However...it comes with so many test strips that you can easily re-test for better clarification.One key method to assure these work properly is to hold the strip OVER the colors, not off to the side.It worked decently for my application. Not great, but ok.I would (still) recommend this to others

Purchased when we realized the science teachers forgot and they students had a lab the next day. Received them same day and saved the day!

The Litmus PH Test Strips set of 320 strips seemed like a good deal, but unfortunately, the results have been quite inconsistent. The strips frequently provided varying readings for the same solution, making it challenging to trust the accuracy of the pH measurements. This inconsistency poses a significant issue, especially for professional or precise use. Additionally, the color indicators are not always easy to distinguish between certain pH levels, leading to confusion. While the quantity is ample, the unreliability and lack of clear, consistent results make these strips fall short in terms of accuracy and dependability." Paper not thick at all and the quality is the worst that I've seen

The product does what its supposes to do. It tests the PH. They are good if you dont need an exact PH but have a range or if you just want to find out an estimate. They are not good if you need a more exact PH, as they measure in steps of 1.Some colors are hard to identify on the paper.

Has everything you need to test liquids including a plastic dropper.

So I first used this on my tap water which is pretty neutral (dark yellowish color on ph strip) It looked as if nothing changed but when i looked closer the color of the paper is fairly close to that of a neutral ph level then under the light I noticed a slight green tinge. I didnt know if these worked properly but after testing with different solutions of baking soda and vinegar I can confirm it works great. Hard to tell just how accurate your solution is, obviously with the colors being subject to interpretation i.e. how one actually sees colors or the type of light that its under. But for general purposes this is cost effective and works great. Thanks
