YINMIK Food pH Meter Digital pH Meters with Calibration Solution pH Level Tester for Fermentation pH Food Meter for Dough Sushi Rice Fermenting Sausage Kombucha Meat Soap Cheese Cosmetic and Water

Easy to use and calibrate. I bought a cheaper one and it didn't work at all, whereas this one worked immediately out of the box and was very accurate and easy to read. It also reads temperature which is helpful. It gives good instructions for storage and I like that it can replace the tip. I would say overall it's worth it to spend the money on the better reader than the cheap $8 readers.

It’s not what I’d consider lab or commercial grade, but it will serve for hobbyists and home cooks. I intend to use it for nutrient solutions for my peppers and tomatoes. Maybe someday I’ll get a bluelabs or a Hannah. Until then, this is economical and seems accurate enough. I’d say calibration often and forget the last digit, and you should be good to go.

Piece of junk. Calibrated it, used it once, and it seemed fine. Tried using it again and the sensor tip snapped off after barely touching it. Don’t waste your money.

UPDATE: After my review was posted, the company did reach out to me and they sent me a full refund for this item. While I still would not recommend the tester, based on it's performance, I do appreciate the good customer service. Very frustrated. Received this product Oct. 30th, didn't start using it until late November/December, used it a total of 15 times. Tried to use it again yesterday and it doesn't work at all. It was showing an error code, but there's no paperwork with a "key" to tell us what that means or how to resolve it. Reading remains 0, regardless of what we do. For the amount we paid for this, we would have hoped it would last a good bit longer than a couple of months. We need it for our food business, and it's really let us down.

Je trouve que le taux de ph est vraiment chambrenlant, difficile avec le mouvement des résultats d'en dire d'un outils avec un résultat qui n'est pas vraiment surs. Difficile à expliquer. Même pour l'ajustement vraiment pas sure des résultats si vraiment sont résultats est bon.
