Hydrion Ph Paper (93) with Dispenser and Color Chart - Full Range Insta Chek ph- 0-13

Simple and accurate enough for what it is. I test the accuracy by comparing readings on vinegar vs lemon juice because those are alreasy well established online. These showed they were both about right color wise.Remember to check them right away after getting wet.If you need exact readings then get an expensive meter. For creating a pickle for animal hides it worked great. I successfully preserved a few small game furs in a pickle using this to monitor the PH.

something that works all the time. Keep it out sun light

I was very satisfied with this product.I use a pair of hemostats to hold a piece of the strip. When I’m done I rinse, dry and put a new strip on the clip for the next day.I also purchased a brand that was individual strips on a plastic stick and another that was like a match book style. Neither of those recent 2 worked as well as the Hydrion.Hopefully this batch will be as good as it was before.

The paper was just a little too thin. Came apart in mouth. But all in all I like it.

The 3 pH strips shown in the photo were diluted vinegar, dilute sodium hydroxide and diluted sulfuric acid. The pHs seemed accurate at 3,13+, and 0 respectively. I also have some mid range strips from same company that measure pH 5-8 which I plan for buffers. These strips cover a wider range and will help me manage acidic or alkaline waste.

Thanks

Opened and looks like it is all damp and green!! Shouldn’t it be yellow? Would like my money back!

Less waste and more convenient than booklets of tear off strips, been using this exact product for years, feed the tape through the side then tape it shut to keep it from coming open in your pocket or when you drop it. Pull up against the protruding tab to easily tear off however much you need while leaving a pigtail for next time.I tape a strip of bright ribbon to it to make it easier to find amid the clutter on my desk or wherever I absentmindedly leave it.For the sake of consistency, I dip an inert toothpick sized piece of plastic into the solution and put barely a drop on the tape, also minimizes waste in the long run.
