I think I see what you're saying... The 4 head doser has a free head that is part of the entire GHL KH director system. So THAT can be used for dosing. But since my kamoer is a SEPARATE doser, there is no way for the diretor to communicate with it. There fore I woudl need a central 'brain' the connects them all like a profilux. makes sense now
Yes, you are correct. But, there very well could be a stand alone ALK monitor that can control the solenoid on your CaRX.
The only two I have any personal experience with is the Trident by Apex (which needs the head unit even if you only want to monitor) and the GHL KHD. This will work as a stand alone ALK meter/controller, has a spare dosing head to use as you please, and can control a slave doser if you need more dosing heads.
I have the KHD, and a second 2.1 Doser, with both set up as slaves and controller by the GHL P4 .
