PH and Conductivity Sensors-What are you using?
We are looking to monitor PH and Conductivity. Anyone doing this and if so what are you using. I am looking for 4-20 or0-10VDC.
If you can't fix it with JB Weld, Duct Tape, and Ty Wire it has to be replaced.
No good deed goes unpunished.
If you want to take off friday to go fishing then make sure you train your helper right.

Conductivity only, need accessory board for the 4-20mA output

The Megatron looks pretty decent and has a number of options. We have one of these, but an OEM setup, no remote tie in yet. Honestly I like the setup of this one better overall. Conductivity probe only goes in one way, flow sensor in clear setup.
Either way protect them both from excessive heat/direct sunlight. We've built covers for all of ours as they tend to die prematurely w/o them.
You monitoring PH to verify the chemical feed is working or you actually controlling off of it as well?"How it can be considered "Open" is beyond me. Calling it "voyeur-ed" would be more accurate." pka LeroyMac, SkyIsBlue, fka Freddy-B, Mongo, IndyBlue
