Need a favour please
 

I've got a problem with either my ORP controller or my probe, and my mV is constantly at 000 in RO/DI/Tap/Tank/Vinegar. Wondering if anybody in town would be gracious enough to let me bring over my ORP probe and plug it into your controller to see if I get a reading. If I do, then it's the controller that's bad. If I don't get a reading, then I need a new probe. Please PM me if you are free and willing, I'm in the NW.

Thanks in advance.
