Try Diagraph and Nissen. (Those are the companies that make the markers we buy, but I'm sure there must be some others)
Our Markal paint mrkers are certified as "low chloride" so you might get what you want from them. I'm not sure if Diagraph gives you any choices.
I do have to say that I think the Diagraph GP-X markers work better than the Nissen - but that might be because the Nissen are the low-chloride type.
