I'm not here to debate you
The point of my posts isn't to debate with you, but to correct misinformation. Whether you in particular take on board what I say doesn't matter much to me.
That people coming to ICMag for info have a counter balance to some of the misconceptions you are putting out here, is what's important. I've said my piece on pretty much every one of those, so that's it from me. Take care.

That Ph pen's ok. It's a manual one so you have to put it into calibration fluid and turn the little screwdriver til it reads the same as the fluid. Build quality isn't great, so just be careful not to drop it on the floor or into water.
Here's one with temperature compensation for £20 which is important when measuring EC. Water measures differently at varying temperatures, so it's worth paying the extra fiver for one with that function.
Personally I'd get This + This + delivery for £25
