Tracer Gas Leak Detector

You are here


Tracer Gas Leak Detector

The LD9-TG features sensor technology designed to detect a 5% hydrogen / 95% nitrogen tracer gas mixture. The LD9-TG’s full color liquid crystal display (LCD) and sweep mode function convey messages, graphics, and prompts to help technicians locate the source of a leak and ensure the leak detector is always at optimal performance. Detects leaks as small as 0.5 ounces/year for R134a and .015 ounces/year for R1234yf. 

The UV wavelength technology is used with tracer gas instead of liquid refrigerant to locate system leaks. The LD9-TG is compatible with most hydrogen-based tracer gases. 10-year sensor life. A patented 3 LED inspection light aids in locating and inspecting suspected leak sources.

Tracer gas sold separately. Meets SAE J2970 industry standards.
