Nutrient Delivery System – Which Doser Do I Pick? Dosatron or Etatron?

If you are not sure which dosers should go into your Nutrient Delivery System (NDS), here’s some helpful information.

Dosatron Water-Powered Dosers

Dosatrons are the perfect choice for injection rates of 1:3000 (0.25 tsp/gal and 1.25 mL/gal) to 1:10 (75 tsp/gal and 375 mL/gal) and are available in the Lo-Flo and Hi-Flo NDS Series. Dosatron features include:

  • Automate the nutrient delivery process, so it accurately dispenses the desired solution
  • Can utilize up to eight (8) different nutrients, additives, or supplements, plus a pH adjuster for a perfect, well-blended solution
  • Make the time draining practice of “measure and pour” a thing of the past
  • Save you time and money by eliminating hand mixing
  • Offer four (4) different modular kits in both the Lo-Flo and Hi-Flow


If you want 1 mL or less per gallon, pick an electric Etatron metering pump which, if needed, can easily reach as low as 0.25 mL per gallon. And they are great for super-concentrated additives. With Etatrons you can:

  • Adjust the amount dispensed with every stroke
  • Dial into micro-dose, down to 0.25 mL per gal
  • Have the ultimate in reliability and functionality in one system

Blending the Etatron eOne Micro-Doser and the Dosatron Lo- and Hi-Flo Dosers creates the perfect combination to customize a delivery system for your specific applications. The blending of these dosers brings the ultimate in reliability and functionality, in one NDS system!
