The Redball® Spray Monitor is a simple gauge that allows you to visually monitor proper flow rate of your liquid fertilizer and herbicide applications. It shows immediately if a nozzle becomes plugged as little as 10% and it tells you, at a glance, any variation in your application rate.
Redball® Spray Monitors have no mechanical or electronic parts that could malfunction. Manufactured of a high-impact plastic, they are virtually unaffected by chemical corrosion.
Rather than paying hundreds of dollars for electronic monitoring, get a Redball® Spray Monitor. It'll do the job accurately and affordably.
