TRIXES Litmus pH 1 to 14 Test Paper Book 80 Strips

Arrived quickly and was as described.The small chart I got with it is paper with a glossy coating. The paper is quite thin. I doubt it would stand up to getting wet. It's best to avoid putting the wet testing strips directly on it.The strips seem to work although I can't confirm how accurate they are as I have nothing to test them against. I am also slightly colour blind. I have taken some photos so you can judge for yourselves.I tested them with filtered water from kitchen tap, Apple cider vinegar and Hydrogen peroxide 3%.I should of included the pack of strips and chart in the photos but forget.Overall I am happy with them. I have marked them down to 4 stars because of the thin paper chart.

Basic pH papers. Used by a child but quite simple to follow the chart. Should have ordered more.They need a container in which to hold them, but good value.

Works well, though not as sturdy as the plastic backed ones so makes it harder to hold up against the paper.

The quality is very good!

I need to test my urine daily, the cost of the litmus papers were initially my reason for ordering them. They are simple to use, easy to dispose of and present no issues whatsoever. The Doc's are happy I am keeping a check on things, I am happy it isn't expensive to do so, additionally I get immediate result if I suspect acidity.

Paper stays the same colour so I’m not sure it actually works

Bought these to test a water filter and various other bottled water. It seems they are accurate enough and gets the job done. Plenty of them in the pack which will last a long time if stored properly. They were very cheap as well and I was surprised how well they fare for the price.

We have a hot tub and purchased these after we ran out of pH testing sticks to try as they are about half the price of the ones we usually get. It was a complete waste of money, they don't seem to change colour much no matter what they're dipped in and when trying to compare the strip to the included chart the ink runs on the chart as it isn't laminated, making it even more difficult to read. Save yourself some frustration and money and purchase the strips that are a bit more expensive but that actually work and tell you levels of free chlorine and overall chlorine amounts along with the pH.
