There are better options - like this one from INKBIRD

A 4 in 1 meter

I bought 2 of them ( 1 as backup ) they work well.
They are literally on sale right now on amazon for $19 bucks ( amazon prime member price ).

Yeah, and for my 2 cents the Inkbird ph pen is a much better deal than the other one you were looking at.

I buy bottles of this and save hundreds on meters and it's never out of calibration and doesn't run out of batteries. The only thing these aren't good for are slurry samples.
