💧 Digital Water Quality Tester with Calibration Kit - LiZi pH Meter Review

Ordinary, cheap PSh meter. Measure tap water, etc. will do. When it starts to give incorrect readings, throw it away and buy a new one.

Definitely do not recommend this company. The calibration solution did not solve the problem, although it measured everything in a scientific way. Pros: There are exactly as many advantages as the numbers on the device screen, namely 0.0 Not calibrated. Possibly defective. Some cons: A piece of plastic with a filling. A total disadvantage. The pH of the water does not measure even after calibration.

The purchase is worth the money, they bought a water analyzer that shows ph. I am very satisfied, finally I can control what water I use every day.

Definitely do not recommend this company. The calibration solution did not solve the problem, although it measured everything in a scientific way.

People, be careful! The calibration screw is located inside the tester, which can be reached with a screwdriver But the problem is that the screwdriver hole itself is at a completely different level relative to the screw You have to poke it diagonally there and look for this screw by touch, by touch because at this moment you should monitor the display with an indicator An even bigger problem is that this screw is located on top of some kind of board, and if you poke this board with a…

The device may be good, but after reading the instructions 10 times, I did not understand anything - there are a lot of terms. The entire instruction is a list of excuses why the device will not work correctly. If I understand correctly, then it will always work incorrectly, tk. it is simply impossible to meet all the requirements. Separately, I would like to note that questions arise directly from the packaging. Written - digital PH meter in a case with calibration. Either the device has…

I take care of my health. I decided to check the tap water - I was horrified. How much nonsense is there! Anyone who cares about their own health, I recommend to buy this device and test the water.

You can see from the photo how well it measures. Photo after 30 seconds of active mixing. - I do not advise this to buy, a lot of marriage!

I ordered while I was on a business trip and my son took the order. As a result, by the time I returned and unpacked it, it was already too late to return and I ordered another measuring device, which also turned out to be broken. I strongly recommend avoiding this store.

Ph meter not working. When parsing, I saw that one wire was not soldered. Money thrown away, I do not advise anyone to buy this product, because the build quality is disgusting.

I really like the ph meter. Never thought about what kind of water we drink before. Now I am attentive to this, because there is an opportunity to check. In general, my daughters bought it, she is fond of aquarism, she simply needs a PH-meter.

I did it according to the instructions: I took 250 ml of distilled water with a temperature of 26 degrees, diluted the bag with ph 4.01. The device showed 3.5. I tried to turn the screw - the values ​​\u200b\u200bdid not change. I did a similar operation with the second solution (ph 6.86) - the result is 6.0 Well, how to use this tester then? By the way, turning the screw is a separate art: it is easier to remove the upper black part with batteries, so that at least you can see where to insert…

In general, the device is excellent. Measures correctly. But there were a couple of moments that spoiled the impression. The first opening took about 15 minutes of fiddling with a knife. But there was no further problem. Maybe I just got an old batch. There is also a hole for calibrating with a screwdriver on one side, and a screen on the other. Screwdriver and bolt are small, it is inconvenient to calibrate alone. But probably. The measurements themselves are convenient, without problems. For…
