Te Pari Revolution Smart Dosing Guns

by Te Pari

The Electronic Auto Dosing Gun system that will redefine animal treatment! Get the exact dose for each animal!

Just like the cordless drill hit the building industry by storm, the battery powered Te Pari Revolution Dosing Gun is set to do the same. With the dosage set on the digital keypad then delivered courtesy of an easy pull trigger, plus the balanced design that fits nicely in the hand, you have ground-breaking not hand breaking new technology. Overwhelming feedback from farmers who have tested it already, is that it is just so easy to use and significantly cuts down on dosing time.

The Revolution Dosing Gun, when combined with a compatible Scale indicators or software system forms an integrated animal management system. The Scale calibrates the dose rate and transmits it wirelessly directly to the Te Pari Dosing Gun. 

Be sure to watch the video of the system in action!


The battery-powered electric motor drives the piston forward and back. The operator can adjust the delivery and refill speeds to suit the situation. A single power unit can be fitted with either a 70ml, 14ml or 6ml barrel, making the dosing gun a truly multipurpose device. Other items of interest may be the drench hook and replacement batteries
