Common Automotive Applications by Detection Method
| Detection Method | Typical Application | Why Premium Features Matter |
|---|---|---|
| Electronic Sweep Mode | Pinpointing exact leak location along evaporator coil fins, condenser tube connections, or compressor shaft seals where precise identification saves repair time | Sweep mode line graph reveals leak direction – moving probe back and forth shows refrigerant level changes to trace leak to exact source point |
| UV Dye Confirmation | High-end luxury vehicles and dealership warranty work requiring documented visual proof of leak location before authorizing component replacement | 3 UV LEDs illuminate fluorescent dye at leak sites, providing photographic evidence that satisfies insurance claims and warranty administrators |
| Difficult Diagnostic Cases | Intermittent leaks, micro-leaks on brazing joints, and evaporator core leaks buried behind dashboards requiring absolute confirmation before disassembly | Bar graph and sweep modes work together – bar graph finds general area, sweep mode pinpoints exact spot, reducing comebacks from misdiagnosis |
