Can this be calibareted for more acidic solutions, say pH 2?

I would have thought once the device had been calibrated at 4.0ph and 8.0ph for accuracy then it should show your readings for 2.0ph +/- whatever. If I were to stick the device into a glass of tap water it would show me the exact readings for my tap water no matter how acidic or alkaline it was.

Do you get solutions with it

I got two diff solutions to help calibrate
