The Hydro Systems 1190 AutoDose is a programmable automated dosing system that requires little day-to-day effort and eliminates human error in dosing amounts. Wall mount, compact size and AC power makes it easy to install where it is needed most, and you can essentially plug it in and forget about it! As long as there are chemicals and power, the unit will operate on your programming schedule with no day-to-day interaction. Perfect for drain cleaning, cooling towers, boilers, lubrication systems, pools, and other areas that need regular frequent dosing of maintenance chemicals to keep them clean. This version of the Hydro Systems AutoDose is designed to be mounted on a wall or flat surface.
