Simplify your nutrients by directly installing Dosatron Doser into the water supply line

Installed directly in the water supply line, the Dosatron operates by using water pressure as the power source. The water activates the Dosatron, which takes up the required percentage of concentrate. Inside the Dosatron, the concentrate is mixed with the water. The water pressure forces the solution downstream. Operating pressure range is 2.2 to 116 PSI and water flow range is 2.2 to 40 GPM. Injection capabilities of 1:100 to 1:20. Includes mounting bracket, suction hose, bypass, union, weighted strainer, and quick start guide.

Hydroponics requires exact, repeatable results. The Dosatron D8RE5VFBPHY Hi-Flo doser is perfect for the indoor grower.

It is water-powered, so no electricity is needed and compared to other dosing products on the market, it is easy to maintain and keep in service — saving you time and money. It’s easy to adjust your setting, just turn the dial and set the necessary dosage rate.

The D8RE5VFBPHY includes an easy-to-use bypass and a union for simple installation with the Nutrient Delivery System (NDS). It has a flow range of 2.2 to 40 GPM, a ratio range of 1:100 to 1:20, (37.5 to 190 mL/gal and 7.5 to 38 tsp/gal) and a max pressure of 116 PSI.

Dosatron Chemical Injectors Are Water-Powered So No Electricity Is Needed.

Dosatron water-powered, non-electric chemical injectors are the easiest, most reliable way to accurately inject chemicals into water lines. Dosatron injectors work using volumetric proportioning, ensuring that the chemical mixture remains the same regardless of variations in pressure and flow.

When water enters the injector, it triggers the hydraulic motor, which begins moving up and down inside the body of the injector. On the up stroke, the Dosatron draws fluid up from the concentrate tank in an action similar to a hypodermic syringe. On the down stroke, the concentrate is displaced into the mixing chamber, where it is mixed with the water flowing through the unit. Then the water-and-chemical mixture is discharged into the water lines.
