- Divolight Digital PH Meter - High Accuracy Digital Water Quality Tester with 0-14 PH Measurement Range for Household Drinking, Pool and Aquarium with ATC

I recently purchased the Water Tester PH Meter, and I couldn't be happier with its performance. The quality of this device is evident right from the moment you hold it. It feels sturdy and well-built, instilling confidence in its durability. When it comes to performance, this PH meter truly shines. It delivers high accuracy with a 0.01 PH measurement range, making it perfect for a wide range of applications, from testing household drinking water to maintaining the water quality in my pool and aquarium. One of the standout features is its automatic temperature compensation (ATC), which ensures that the pH readings remain accurate even in varying temperature conditions. This is crucial for obtaining reliable results. What's more, this PH meter offers fantastic value for money. Its accuracy and ease of use make it a valuable tool for anyone concerned about water quality. It has already saved me time and money by providing precise readings, preventing any guesswork. Speaking of accuracy, I was pleasantly surprised when I compared its readings to traditional strip pH paper. The results were consistent, with a margin of plus or minus 1. But what truly impressed me was how it solved a specific problem I had with my countertop RO water system. My RO system had always indicated that it released water at 12-14 TDS, and I relied on traditional strip pH paper to check the pH levels. However, it was a hit-and-miss process. Then, I decided to put this PH meter to the test. I was thrilled to find that it was not only easy to use but also incredibly accurate. It confirmed its pH readings matched those of the strip pH paper. Knowing that I can trust this meter's readings gives me peace of mind about the water I use. In summary, the Water Tester PH Meter is a top-notch tool that delivers quality, accuracy, and value for money. It has made water testing a breeze, and it even solved a specific problem I had with my RO system. I highly recommend it to anyone in need of a reliable pH measurement device.

I bought the Digital PH Meter to monitor the water quality in my aquarium and pool, and I’m genuinely impressed by how well it performs! - **Pinpoint Accuracy**: The readings are spot-on every time. With a 0.01 pH resolution, I can trust the results whether I’m testing drinking water or my fish tank. - **Automatic Temperature Compensation (ATC)**: This feature is a game-changer! It adjusts for water temperature automatically, so I don’t have to worry about skewed readings. - **Quick & Simple Operation**: Just dip it in, stir gently, and wait a few seconds. The reading stabilizes fast and is clearly visible on the digital display. - **Portable & Convenient**: It’s compact enough to carry around, and the included case keeps it protected. I’ve taken it camping and even used it for hydroponics. - **Ready to Go**: It came pre-calibrated with batteries and buffer powders included—no setup hassle at all. Whether you're a hobbyist, a pool owner, or just want to ensure your drinking water is safe, this pH meter is a must-have.

Better than drops or dip-sticks. Wish I had gotten a higher-end unit that tested for more variables.

I was excited about this product.... Untill i got it. The directions seemed to be written by AI. Completely incomprehensible. I had to go onto YouTube to find a calibration video since I had never done it before. The instructions were useless. But I found a video and matched it up best I could with the directions the meter came with. I did the calibration correctly according to the written instructions that came in the box. But every time I tried to test any sample of water, the readings were all over the place. Nothing consistent or accurate. I did everything right. Making sure to wash the tip off with distilled water and such. Nothing helped.. I even decided to do little experiments with two samples of distilled water in the similar ceramic cups. The ph readings of both cups was wildly different. And the number would jump several numbers if I swirled the meter in the water. Often the meter would time out and shut off before I got a stable number reading. The number would just rise and fall without reason. I even tried to take a reading of the calibration solution again. The 6.86 solution literally has a ph of 6.86. That's the point. Nope. The meter was waaaay off and each testing of the solution was different. I tried calibrating the meter again, but it refused to. All in all, this was a complete waste of money. No way of telling if any of the ph readings are correct. I'm gonna go out and get pH test strips. The are less accurate but more consistent. Don't waste your time on this product.

This is an excellent pH meter with unheard of accuracy for a meter costing @ $15! It outperforms a meter I paid $50 for. I wasn't sure, and I hoped that they had used tri-color LED's for the backlighting so that the backlighting would change color with the pH reading, but that is not the case; green is the backlight color. (That would have been TOO perfect!) Even so, this meter with .01 accuracy is a steal at a ridiculously affordable price!

This is way better than the pool dip sticks. It’s not an instant reading, but after about 30 seconds, gives you a good reading

This meter came with very sketchy instructions. After some time on the internet, I was able to garner a better understanding of how to set the meter up properly. It also neglected to tell you that the element is very touchy and requires constant moisture. I suggest doing some research before ordering because you will want to include additional PH packets, a moisturizing solution, and some 8 oz bottles to store the calibrating solutions.

It's nice
