Hewlett Packard – HP 24540-80012 – Agilent 6890 Gas Chromatograph RS-232/modem
I bought this from the local University surplus store. It is sealed in the original bag, but I can see that the bigger connector end has some oily residue on it.. must be from age? I’m sure it’ll clean off with some alcohol. This part number comes up via a Google search as belonging to an HP/Agilent 6890 Gas Chromatograph, but it may be that it is appropriate for other models too… do your homework!.
