Excellent for Greenhouse Users!

The Dosatron® D14MZ2 Injector without a bypass dispenses a wide range of solutions including fertilizers, fungicides, pesticides, disinfectants and algaecides. This injector replaces the popular DI16 Model. Installed directly in the water supply line and uses water pressure as its power source.

Water activates the Dosatron®, which takes the required concentrate percentage and mixes it with water. The water pressure forces the solution downstream. The dose of concentrate is directly proportional to the volume of water entering the Dosatron®, regardless of variations in flow or pressure in the main line.

    Recommended Purchase

    Review by on Sep 27, 2015

    Very pleased with product. After years of hauling around a hand held manual fertilizer pump, this is a very welcome labor saving device. Product meets expectations. I've only been using it for a week or 2 - but so far - so good. I would not hesitate to recommend the product. There was a bit of a hold up with some UPS internal issues around delivery, but QC customer service followed the issue closely and was responsive to my concerns.

    only one minor problem

    Review by on May 4, 2014

    I make a concentrate and operate at a 1:64 dilution. My last one worked fine until I left it outside in freezing temperatures and cracked it... so I purchased this replacement. The one and only *minor* problem is that when operating at a 1:64 dilution attached to the Dosatron rolling cart, I can't unscrew the concentrate container to add more without removing the Dosatron. Even screwing it back to a 1:1 dilution doesn't give sufficient space to replenish the concentrate. I had to remove the Dosatron from the cart to replace the concentrate. Other than that, this product is spectacular.
