I’ve tested multiple stuff and it works well. I don’t know for how long it will though. I’ve bought pH strips before and they stop working after awhile. Could be air exposure or just got old. But this paper is nice.

Hydrion may be less accurate than I anticipated.

Reviewed in the United States 🇺🇸 on September 4, 2022

I've not tested the paper fully but a preliminary test indicated it may not be as accurate as I expected. Otherwise, everything about it is good. I intend to test 5 different levels of known acidity. That should provide useful information concerning the accuracy of the paper.

Low Precision

Reviewed in the United States 🇺🇸 on January 28, 2017

Verified Purchase

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.

Arrived with a blu-ish color. Not good

Reviewed in the United States 🇺🇸 on May 13, 2022

Verified Purchase

I taught Biology for 30 years so I am very familiar with pH paper. It is supposed to be orange or tangerine in color. If it has a blue or green tint to it, it 's been exposed to something alkaline. The reading on my tap water was in agreement with another test so I guess it's okay, but the roll should have been clean.
