Setup is easy. Calibrate pH at 1, 2, or 3 points in tenths, hundredths,
or thousandths, then set target reading for pH and ORP with dosing
activation set ABOVE or BELOW target readings. Also set your own
CAUTION and CRITICAL levels. The DL125 will gently maintain
assigned pH/ORP values. Full duplex Wi-Fi allows interaction with
unit through your portal from anywhere in the world.
