|Slope out of Spec.|
I have been having issues with the slope reading when calibrating the meter. The slope is consistantly low. We noticed that the mV readings are all low as well(measured with pH buffer 7 and 4). Could this affect our slope reading? If so, is there a calibration buffer for mV?

What is this technology exactly? How does it work? What material is the pH bulb? What's the actual thing that happens in bulb the bulb? Can u send me details with images?
