GHL Doser 2.1 Standalone Model, can be linked to the Profilux 4 if you want. Used for Freshwater plant solutions for a bit but did not get extensive use. Will include the John Guest fittings used on the solution bottles (not shown). Comes with one Magnetic stirrer that you can have the doser turn on to mix periodically (stir bar is not shown). Power cord and adapter is included. Will also include a usb cable to make it simpler to program.
Prefer local meetup/pickup in Worcester/Framingham MA area but will ship if you want.
