SA-77® Electric Samplers; U-Control Series

Brand: Peterson Instruments

SA-77 designed the U-Control line of Samplers and Accessories so that customers could have an economical way to add automatic sampling to existing or new process applications that already have a control system for that process. 

If your process already has a PLC, Programmable SCADA Control RTU, DCS or even basic relay logic... SA-77 and Peterson Instruments will give you the required Programming Narrative so that you can develop your own custom sampling application. 

We have full examples and drawing to get you started.
