Hallo!
Yes I think so!
Funny how my thread has developed!
With what kind of measurement you all work to measure pH?
I m thinking of a photometer …
I have a Martini Milwaukee two point electrical meter, but I have to “fix” it every week a new, that I don´t like so much …
And the drop tests have just a few steps and I must look out for the color of dark water .. so my painters head has to mix (or remix) the colors …..
