How do I make a Poll?

I have seen various posts about meters, and thought it would be good to make a poll so we can get some old head opinions on meters. I have a Hanna but between the calibration solutions and the electrodes its almost the cost of a new meter ( BTW they need to be calibrated most of the time too ) Stupid if you ask me, and similar to selling a GPS with no maps. I wanted to get opinions on a few meters, including single and dual calibration and how much it may effect accuracy. As well as alternatives towards calibration solutions, for instance if anyone has been able to test commonly avalible products for ph levels and see if any are reliably equivalent to say 7.01 or so forth. And mabye after enough reading write a guide.

No interest. Ok.

It's a tool available when you make a new thread. Look around you will see it.

Thank you, off to measuring random shit.
