I am looking about for a replacement probe for my Dupla Pro controller.

Not an easy thing to find apparently....

Does anyone know if any standard BNC probe will work with the dupla kit?

Many thanks in advance

Yes. I use a Milwaukee probe with a Weipro ph controller.

I don't know about your specific kit, but pH probes are generally universal. I am using a BRS pH probe with my Neptune Apex. The one thing to watch out for is that some are designed for intermediate use and are not designed for continuous immersion.
