possible PH problem?

can anyone answer my question about the meter i have for the time being? with a two point calibration does it need two solutions to get it on a correct path? common sense says yes but who knows!

yes it does, needs to be able to read it to set it

thanks alot for the input!

2 point calibration can be a bit tidious but well worth it if you want the most accurate readings your meter has to offer.

Thought I did. Yes you need 2 solutions for 2 point calibration. Usually a 4.01 and 7.01. The temp of the solution is key to get accurate calibration. Most solutions have a chart right on the bottle. Calibrate at 4. Then at 7. Go back and adjust 4 again. You you will go back and forth a few times to get it really tuned in..........
