I want to know if it is possible to calibrate the ORP probe with 400mv calibration solution by changing the 50 ohms resistor?? Cause it's difficult to find a 470mv calibration solution in my local dealer.

If so, what resistor I need?

Thank Eric

I don't think so.
We can interpolate mathematically to find out the corresponding value for 470mV
