The Quick Detect uses disposable cartridges in conjunction with flow measurement to determine the presence of active sealant. QuickDetect is designed to mimic an A/C leak. If sealant is present in the system, it will quickly solidify in the disposable test cartridge and cause the flow meter to show « no flow ».
