Hello:
I bought a pinpoint PH moniter used and am trying to calibrate it. I cannot seem to get the numbers to 7 or 10 while calibrating the unit. I have the probe in the solution and am cranking the appropriate screw to adjust the display and no matter how far I turn the screw it will not reach PH 10 or 7 without adjusting the wrong screw. Does this meen that the probe is bad? Does anyone know where to buy good probes for these units for less than 50 bucks? Would home depo sell these probes?
Thanks for the help.
