Robinair Premium Refrigerant Leak Detector — LD7

1 x LD7 Detector with UV LEDs and carrying case

Premium detector with bar graph and sweep modes for pinpoint accuracy. 3 UV LEDs for dye detection, color display, inspection light. 10-year sensor, .05 oz/yr R-1234yf/R-134a sensitivity.

LD7 Premium Refrigerant Leak Detector

Dual visualization modes with bar graph showing refrigerant concentration and sweep mode line graph for tracing back-and-forth to pinpoint exact leak sources
3 UV LED system operating at 395-415 nanometers illuminates fluorescent dye for dual-method leak confirmation on systems using UV tracer additives
Visual probe LED alarm at sensor tip provides immediate leak indication visible in tight spaces where main display cannot be seen during inspection
10-year sensor stability maintains .05 oz/yr R-134a and .0123 oz/yr R-1234yf detection sensitivity with instantaneous response throughout service life
Professional carrying case organizes detector, 4 AA batteries, leak test vial, 5 replacement filters, and accessories for mobile service or shop storage

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
