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

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.

Works great, but I actually went back to the paper ph tester strips. The calibration directions were almost clear ( frustrating a bit) and the fact that you HAVE TO KEEP THE TIP MOIST AT ALL TIMES, means that if you’re not using it daily or weekly, you have to remember to re-moisten the sponge at the tip of the cap.

As advertise.

I really like this pH meter. It is easy to use, easy to read and helps me determine when my ferments are ready.

Good for cost , I don’t think it’s always accurate . Kinda tricky, jumps around sometimes but ok for my purpose
