Digital pH Meter Tester Pen With 3 Calibration Powders, 0.01 Accuracy, Pocket Size, LCD Display for Household Drinking, Pool and Aquarium

This digital pH meter is incredibly useful and accurate! I’ve used it for testing water in my aquarium, pool, and even household drinking water, and it delivers fast, consistent readings every time. The 0.01 accuracy really gives peace of mind, and the LCD display is clear and easy to read. It also comes with 3 calibration powders, which makes setup simple even if you’re not super technical. This product contributes to the environment and really good quality. Plus, the compact, pocket-size design is a bonus for easy storage and portability. I definitely recommend this to everyone who needs reliable pH testing at home!

For anyone with hobbies that depend on the pH of something, this little digital pH pen is a fantastic tool to have in your toolbox. It takes all the guesswork out of the process. I use it to keep the water in our fish tank just right, and it’s super easy to use. One thing I really like is that it also measures the temperature at the same time as the pH, ensuring my heater/thermometer is working as expected. It comes with calibration powders so that you know your readings are really accurate. This meter is exactly what I was looking for: simple, effective, and I highly recommend.

I honestly believe that most of the good reviews of this dud only THINK that it is working because they're not testing its accuracy. Total junk. I'd give it 2 stars if it worked AT ALL, but I can't. First of all, the instructions are very badly translated from Chinese and are confusing at best. And then, when attempting to calibrate (says pre-calibrated, but no way I'm I going to trust that from a cheap Chinese factory), the unit kept grabbing 6.86 while attempting to set the high point in the 9.18 solution. Because this cheapo unit only comes with ONE set of calibration buffer salts, and I wasn't sure if the issue was with the 9.18 salt packet, I then made my own stock solution that was slightly more alkaline than 9.18. When I attempted to calibrate in that, this piece of junk still kept trying to set at 6.86. Needless to say, I'm returning this thing. Shame on me for relying on a cheap Chinese junk factory to manufacture a precision piece of equipment. I hope you don't make the same mistake!

Purchased this PH meter to see how it would work with my well water but more importantly the hot tub water to determine how it works for adding Ph increase or decrease chemical to it to keep it its in best neutral state. It worked very well and compared almost exactly as the litmus paper that comes with the hot tub. It also helps me feel comfortable about our drinking water. Also the test powder to verify the device also was easy to use. Would recommend this device.

Out of the box it may not be accurate otherwise it has a good display the easily read.
