Neptune Systems PM1 UsedC pH/ORP Probe Module

This particular one has a little bit of rust on the BNC port used for pH/ORP. This may need replacement parts or just to be used for scrap parts. This product was used for years and there is no warranty or guarentee. Sold as is with no wires or cables. It was working the last time I used it a few years ago.
