High Precision: Accuracy: ± 0.1 pH; Resolution: 0.01 pH. With highly sensitive sensors and intelligent chips, the pH tester delivers accurate results always. Smart ATC serve as guarantees reliable readings even in cold or hot conditions
Fast & Easy Test: Start the meter, immerse the sensors within the test sample, and gently stir. The test results will come in seconds. Then press the “HOLD” button to fasten the readings. High-contrast LCD screen provides a clear display for simple recording Pawfly
Convenient Calibration: Come with 9 bags of pH buffer powder for quick calibration. No special skills or complicated procedures required! Effortlessly handle the pH test pen’s accuracy for lasting performance
Wide Application: Engineered for comprehensive food testing – from sourdough and bread to cheese, sausages, meat, and rice. Also excellent at measuring the pH of liquids including water, wine, and beer, plus cosmetics and semi-solid substances. This is a handy pH meter if you need to check the pH in food preparation. Since I had nothing to compare the results to, I first did the calibration according to the instructions. It comes with packets for pH 4.0, 6.86, and 9.18 at 25 degrees C. Dissolve one into 250ml of water (supposed to be deionized water, but I just used filtered water). After inserting the probe into the water, press the TEMP/CAL button for 3s and it will calibrate for the given pH. Do this for each one. Then you can start testing liquids for pH and temperature (also selectable between Celsius and farenheit). The device also has a hold button to lock the display reading. I checked the pH of our tap water and it was slightly acidic, but I don’t have another method of verifying the readings. Overall, it is easy to use Pawfly 

I like the fact that I’m not pulling little strips of litmus paper out and comparing to a chart to see where it matches. I mean, I’m not colorblind so it’s not an issue but someone who was? What do they do? Well, I bet this would solve that problem right then and there.

But either way, it’s nice getting a good clear reading and not having to guess…is it between red and redder? Or is it yellowish green? Like you do with litmus. It seems to fairly accurate, certainly good enough for its advertised purposes.

But what about home/hobby chemistry? So far, so good. I mean, I would suggest putting this in some fuming nitric acid or the like but I think it would be fine for anything that doesn’t dissolve plastic (it doesn’t like acetone… dont ask how I know).

So yeah, neat little gadget. It included several packets of powder, each to be mixed with an exact amount of distilled water (important that it is distilled) to creat a calibrating solution of acid, base, and neutral solutions. You get 4 packets of each I think, which is enough to make a LOT of solution.
