The R-1 liquid fertilizer injector combines the durability that SMITH products are well known for
yet at a very affordable price.
Built nearly entirely from highly engineered plastics, the R-1 is ideal for portable hand watering
applications but can also be permanently installed as well.
The R-1 can be used to inject any combination of liquid fertilizers, fungicides, chelates, insecticides
or mild acids. Since each R-1 is TWO-INJECTORS-IN-ONE, simultaneous injection of two chemical mixes
can be accomplished if so desired.
Each injector on the R-1 is permanently set at 1:100 proportion to simplify the design and minimize
proportion setting errors.
Easily removable check valve inserts (see figure 1) are provided for quick O-ring change, which is the only routine
maintenance ever required.
