I have a lab grade pH probe monitor that is accurate to 1/100th accuracy (ie 8.28 pH) and it has a temperature adjustment for higher degree of accuracy.
This unit is about 4 years old but still working very well. I just bought a brand new pH probe for this unit thats still in the box. I've upgraded to a controller so don't need this anymore.
