Pen-style Phmeter: suggestions?

[Kayzah]

Hi guys

I want to get a pH meter (preferably a pen-style).

I don't need something fancy, just a low-key product which will do his job properly.

I've read somewhere here, about going for a two-point calibration pH-meter or something along those lines. What is that? And Why?

Please advise.

Thank you in advance.

This is the only one I know of that’s used regularly in the aquarium trade.
