Julie, the price was a bottle of wine and a bottle of skeeter pee!!
Corinth, thanks for the info, that is my luck getting an obsolete item
Aaron, that does look like the one, how do you calibrate it? In 7 solution it read 7.3 and in 10 solution it read 9.9. I have it in 4 solution now for storing, does that sound ok? It should work for me, still trying to get up to entry level
Scott: Try using PH 7 solution and PH 4.1 solution.
There is a screw in the back you turn to calibrate to these numbers.
I can usually get it bang on these numbers every time.
