But that single test will give you the equivalent of the K2006 a lot cheaper, since you have the K2005.
I'd like to "upgrade" my K2005 with just the FAS-DPD test kit but can't seem to find a supplier online. Does anyone know what the model number is, or a supplier that carries the kit? I still have a pretty good supply of the rest of the reagents for my K2005 so don't really want to buy another "complete" kit just to get the FAS-DPD kit.
