Dosmatic A-12 Mobile Unit
$645.00
We are so excited to be offering the ULTIMATE in fertilizer injection technology. Ask any professional nurseryman what he uses to control his liquid feeding program and he will tell you, "The Dosmatic". How does it work? Water flow drives the main piston. Each 1/2 quart (475 ml) of water flow moves the piston. At the end of the stroke, the inversion mechanism clicks, and the piston changes direction. Each quart (950 ml) of water flow results in two clicks or one complete cycle.
The water-driven main piston is connected to the dosage piston and cylinder. The dosage piston draws chemical from an open container and injects the predetermined amount of chemical into the quart (950 ml) of water that powers the main piston.
Step 1: The up stroke: Water enters the unit with the lower valves closed, forcing the piston up and squeezing the water out of the upper chamber into the mix chamber, then through the outlet. The piston hits the top of the cylinder changing the valve position.
Step 2: The down stroke: The lower valves open, the upper valves close, and water enters the upper chamber forcing the piston down and squeezing water out of the mix chamber through the outlet. The piston hits the bottom of the cylinder and the cycle starts anew. NOW, THAT MAY BE MORE TECHNICAL THAN SOME OF YOU WANTED TO KNOW SO LET US SIMPLIFY........ This is the most accurate fertilizer injector available and it uses no electricity. You can dial the concentration of fertilizer you want to use from the "lockable ratio adjuster". Simply mix your concentrate in the tank, set the ratio you want, turn on the water, and start fertilizing. The ratio will remain constant regardless of your water pressure or the flow rate. This is the last fertilizer injector you will ever buy. If you don't believe us, ask any nursery if they use a DOSMATIC! The answer will be, "YES".
