844 Series Sprayer Controls
The TeeJet 844 Sprayer Control offers spraying advantages
not found in other controllers. Designed with simplicity
in mind, computer-controlled spraying has never been
so easy. Simply set your target application rate and the
unique VisiFlo display on the 844 helps select the right
TeeJet tip for the application. Once spraying begins, the
large display shows application rate, volume sprayed,
system pressure, sprayer speed, and area covered.
The built-in planning tool on the 844 automatically
displays the speed needed to achieve the target rate
with the specified tip. It will also calculate the pressure
necessary for achieving the target application rate when
the speed is entered.
The 844 is available in a complete package with the valves,
cables and sensors needed to put together a total sprayer
control system, or as an individual controller.
