I've just purchased a Hanna PH meter.
In the instructions it says (see pic blow) "To activate, immerse in storage solution for 2 hours."
Does this mean that every time I use it (say once a week) I have to activate it it first for 2 hours then only calibrate ?
Or is this just a first time use thing ?
Any comments appreciated.
