It was good and works perfect

Conforme à la description. Fonctionne très bien

The product looks good. It comes with 3 powdered testers, which you can dissolve in water and use to calibrate. There's also a colorful supplement with pictures and text (in English), featuring excellent- in other words, simple, clear, and understandable- instructions for the product. I read that some users had problems with calibration- mainly with the 10.01 pH solution. I didn't experience such an issue- everything went exactly as described in the user manual. However, I have serious doubts about the accuracy of the readings provided by this pH meter. Despite following the calibration instructions exactly- as soon as I calibrated it with 7, then 4, and finally 10.01 pH- I immediately tested all three solutions again. It showed slight deviations. It did not read any of these solutions with perfect accuracy, and- as I said- this happened just a minute after calibration, in the same solutions, at the same temperature. That's why I’m giving the product 4 stars- for now. I’m still considering whether to return it, but I’m leaning toward keeping it, because the alternative is to buy a higher-quality product- for at least five times the price, which is a bit much for me (personally). Besides, I will be using the product to test the pH of fermented meat (for dry salami/charcuterie, roughly speaking). The range I’m aiming for is 4.9 to 5.2 pH (for fermentation), and I hope that- even if this pH meter is slightly off- it will still give me some idea of the general range I'm in. Better than nothing, right?
