This will allow specific readings as temp, DO, ph, conductivity, level....oh CRUD, I am NOT going to get any work done next week because I am going to be researching instrumentation probes for this now! laugh


Glad to see another control guy here cool I was getting lonely. Maybe we can talk shop! (no one will have a clue)

ML1000 and ML1100 have free software. RSlogix Lite 8.30

Connected Components is also free software. Run like heck from the component screens, unless you like misery wink

I use quite a few of these: RLC HMI
