LD9-TG Robinair Hydrogen Tracer Gas Leak Detector. The Robinair Tracer Gas leak detector gives technicians the tools necessary to use tracer gas in place of refrigerant to find A/C system leaks. The LD9-TG includes a hydrogen gas leak detector with sensor technology designed to detect a 5% hydrogen / 95% nitrogen tracer gas mixture. The detector'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 that the leak detector is always at optimal performance. A patented 3 LED inspection light aids in locating and inspecting suspected leak sources.
