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.

As advertise.

Product was faulty against multiple other pH meters. I tried to contact the company for a replacement but they did not respond even though their instructional pamphlet stated they would respond to inquiries within 24 hrs and guaranteed replacement of faulty units. disappointed in the poor customer service.

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.

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.
