Features: Automatically Calibration: Abandon using a screwdriver to calibrate the meter, you can use calibration function with PH-02 meter, Just simple to press CAL button to finish pH 6.86/4.01/9.18 calibration processes. Fast Accurate Reading: Without much efforts to read a guessing reading compared to use a pH litmus strip, our PH-02 digital pH tester will provide you a very accurate reading up to TWO decimals within minutes. Easy To Use: Just remove the protective cap, drops the meter electrode into the solution to be tested without exceeding the immersion line, stir gently and wait for the reading to stabilize within minutes, read and record pH values on backlight LCD screen. Wide Application: Full measurements of pH 0 - 14.00, its widely applicable to test any liquid's pH level, great for home and laboratory uses, like testing household drinking water, swimming pools, aquariums, spas, hot tub, hydroponics, food, wine and beer making and more. Energy-Saving: The backlight will automatically shut off in 40 seconds after turning on without operation, and the pH meter will be completely automatically shut off in 5 minutes to save battery energy if there's no operation. Specifications: Model: PH-02 Measuring Range: 0-14.0 pH Resolution: 0.1 pH Accuracy: ±0.1 pH（20°C ) Use Environment: RH 95%, 0-50℃（32～176℉ ) Battery: 2×1.5V LR44 cell button Package includes: 1 x PH Meter Tester 1 x User Manual 2 x Calibration Buffer Powder 1 x Storage Case

Ok
Calibration didnt work properly, i followed the instructions perfectly. But when i would add ph up to my solution the pens resding would go down and vise versa. so had to order more powders meaning my test strips are more reliable at this point. Hopefully another calibration will fix the issueEdit: once calibrated properly it works just fine but still needs calibrating near enough every use

Good but expected a bit better
Good product, I did first assume that it could be manually adjusted from the back but after purchasing I found this not to be the case as it is an auto calibration device. It only came with the two ph calibration solutions which was odd because a 3 point calibration requires 3 calibration solutions. So only a 1 point calibration is available.

Value for money
Take a while to get a final measurement and I wish the screen was back lit but for the price it’s great?

Cheap, fast, accurate enough.
Used to keep track of ph in an aquarium after struggling with trying to tell the subtle difference between shades of orangey red.Using this probe is far easier (swish in water), faster (~10 seconds) and accurate (which you can confirm with the calibration solutions) than indicator strips or liquid-based tests.Downsides: while it displays a reading with two decimal places, you need three solutions to calibrate to that accuracy but only two are provided. The calibration procedure isn't particularly clear but the procedure is pretty simple once you work it out (hold button until it flashes, then press the same button again to choose which calibration solution you're using)

Not a pH meter
The product seemed to be an ec meter instead, though the box described it as a pH meter

Great quality
Much better quality than other cheaper ones (like the yellow one). Recommend

Dont waste your money
