Just a terrible product, very upset.

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.

Return my money! Disgusting product and poor quality.

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…

Pros
  • None at all
Cons
  • The whole tester is a flaw

Think carefully before you buy this product

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…

Pros
  • Don't know
Cons
  • Not for home use

A valuable purchase, some advantages!

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.

Pros
  • Excellent device, Instruction in 2022, measures accurately, powders for calibration and batteries included.
Cons
  • not revealed yet.

My money is wasted, the product is terrible.

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!

Pros
  • The best way to spend 500r nowhere.
Cons
  • The tester does not react in any way to manipulations with the calibration screw. At least turn counterclockwise all the way (as indicated by the instructions) there are no changes.

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.

Pros
  • The store has no merits and sells defective, non-working goods.
Cons
  • They brought a broken measuring device twice.

Best thing for the money, glad I did it.

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.

Pros
  • Optimal combination of price and quality
Cons
  • Not

Dissatisfied with this product, bad to use.

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…

Pros
  • shows something Comes with two calibration bags
Cons
  • The calibration screw does not work - you have to keep the error in your head No package 92022

I'm very happy, it really is worth buying.

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…

Pros
  • Great value for money, good set
Cons
  • 1. The solution in the cap dried up, I had to open it with a knife. 2. Inconvenient to calibrate if you are alone
