Spray Controller - Farmscan Primo 400 Spray

Supplier: Farmscan

The Farmscan Primo 400 spray controller is a specificaly designed controller for the horticulture market, but can also be used in the broadacre market.


The emphasis for horticulturel sprayers is on providing improved accuracy and recording for machines which traditionally operate at higher volumes and higher pressures. The benefit for broadacre sprayers is a relaible, cost effective spray controller that is simple to mount and easy to calibrate. Farmscan has designed the Primo 400 Spray Controller for horticultural and broadacre sprayers and is suitable for low /high volume or low /high pressure applications.

Clear and precise information

The Primo 400 clearly displays and records total area covered, total volume used, distance travelled, application rate, ground speed and tank level. For Quality Assurance purposes, the Primo 400 also records start and stop time, actual spraying time and average ground speed. All spray records can be transfered via MC card to an office PC for record keeping and verification of spray jobs.

It also features in-built section controls, on-the-go rate change and once calibrated maintains the application rate selected, regardless of section shut-down or variations in ground speed or pressure. An audiable alarm is activated if there is a rate error or if the tank is low on volume. This helps to achieve the most accurate coverage with every spray by virtually eliminating overspray and underspray.
