For sale is my GHL 2.1 SA 4 head doser Black, in excellent condition. It has performed very well, quite, and always held calibration (I would re-calibrate every 3 months as a pm service and calibration never wandered). Included is the USB cable, 10' of tubing x 4 (never used). I now dose via hydros control hence why I'm selling my doser. I will ship the doser in its original box via ups with tracking provided. If anyone has questions please PM me.
Asking $180 shipped.
