Catch Test allows operator to collect product from up to seven samples and enter exact amounts collected to calibrate flowmeter. Place containers (such as calibration containers) under nozzles to capture product sprayed during test. Flowmeter Calibration may be repeated as many times as needed if all nozzles require testing. By measuring these samples and entering values into system, an accurate flowmeter calibration value is determined.
