ORP probe and Calibration
I got the pintpoint 400mV solution today. My Pintpoint read 20mV lower and the ACIII PRO do not work with that solution. I may have to order the solution from neptune?
I just found out that my pintpoint controller don't have the calibration screw i assumed this is the older model... As i put the probe back into the water, the ORP reading low... Now i am really confuse...

Will cold solution affecting the reading? According to pintpoint the solution should be at 78 degrees but i think it is much lower

Yes, cold will affect the solution. What do you mean it does not work on the Neptune. It should read 400mV like the PinPoint.

The Neptune uses an automated calibration procedurewith two ph solutions saturated with Quinhydrone.
Steve, what you can do is go into Aquanotes Config->Modify Aqua Program ->Tab Configuration. Change the offset value +/- the difference. Can't remember which. Not the best way but gets you in the ballpark. Don't think the slope matters much.

You could just put the ACIII into the 400 mV fluid and see what you get. Whatever it is, you can just manually adjust the value in your mind, if no other way.
