The Te Pari Revolution Injector is a high-workload, battery-powered, easy-to-use, hand-held and fully portable device. It enables accurate delivery of injectable medications across a variety of livestock species. It is light and portable and an entire herd or flock can be injected quickly and efficiently.

As standard the Gun has a 14 ml barrel, small drenching nozzle and the injector nib combined with a handy carrying case. The optional 70ml Barrel can also be fitted to this gun for drenching and pour on.

When combined with the Te Pari Scale indicators it creates an integrated animal management system. The Te Pari Scale calibrates the dose rate and transmits it wirelessly directly to the Te Pari Dosing Gun.
