Does AC3 support negative ORP readings?

jwaltman · 03/08/2008, 10:53 AM

I am trying to use the AC3 to regulate a sulfur nitrate reactor using a solenoid actuated ball valve. I want to target -165 ORP readings to switch open the ball valve; close at -155. This should keep the nitrate-free effluent rate maximized.

Thanks in advance for your help.

There was a thread on this but search is not working at the moment. As I recall there is a trick you can use to get it to work but I don't recall the details. If search starts to work you might try a search in this forum; the thread was just a couple of weeks ago.

Are you using this now? Any changes in the value? I just recently picked up a sulfur denitifier to assist in my nitrate battle.
what is the program code you ended up using for this?

thanks,
