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.

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.

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.

So glad I got these to ease the anxiety I had about fluid loss. The color key was hard to read but thankfully I my husband works in the medical field and could translate. Good way to monitor at home, tons of test strips in each container

So my aim with this pH paper was to measure substances in the acidic range, mostly aiming for acidities of pH2 - pH5. This pH paper is sufficient if precision is not an issue for you. However, the paper came in the color signifying pH4, and it's hard to distinguish colors between pH2 and pH3, pH3 and pH4, and pH4 and pH5; I can imagine that this is also an issue in the alkaline/basic range. I've worked in laboratories and taken lab classes in the past where we used pH paper (with better color distinction, I now know); so I thought these would suffice since I'm aiming for close ranges without too much precision (meaning I might have a target pH of 3.5 - 4.0 (+ or - 0.2 units or something), rather than exact target pHs of, say, pH4.2 or pH2.0, but I found that this pH paper does not afford me with the accuracy or precision I need.I ended up purchasing a pH meter instead after a lot of research on reasonably-priced pH meters sufficient for my needs (I got the Oakton EcoTester pH 2 (pH 2 is the 2nd version of the model, not to be confused with pH2) waterproof meter with 3-point calibration (for which I use pH1.68, pH4.0, and ph7.0 buffers for calibration since I only target the acidic ranges), a 0.0 to 14.0 scale, and 0.1 precision). Keep in mind, meters require maintenance and care, in addition to special solutions and cleaners to extend the life of your meters, and, depending on the meter, must be replaced or have their electrodes/sensors replaced for those with detachable electrodes/sensors; so they require more care and expense than pH paper. I gave the pH paper 3 stars because it does actually react to give color changes - it's just that as designed by the manufacturer, the colors assigned to each pH value are too close in hues to one another for some consecutive pH values.In summary, if you are just trying to test whether something is acidic or basic (alkaline) or you're targeting wide pH ranges, this pH paper will probably suffice for you. However, if you need greater precision or accuracy, save your money and find something else that fits your needs.

good pH paper to determine the acidity of my food culture
