How do I change the value for orp calibration fluid?

Post by dapg8gt »

Is there a way to change the value of the calibration fluid? I know you can alter it for the pH but what about the orp? I want some readily available fluid and most sold cheaply I can find is 400mv not the 470mv recommended.. I found a link on rc of a guy making some equaling 700 but not sure I want to try that one.. What about changing it to the 400? Would the 700mv solution work also? It's bleach based though so I'm not sure if that would affect the probe or not.. Sorry if this has been gone over I couldn't find it after searching the forums..

Or any other links on where you guys using the orp are getting your fluid. I found 470mv at Grainger but it was almost $50 for 500ml..not sure the shelf life on it after its been opened..
