LD9-TGKIT Tracer Gas Leak Detector Service Kit

Leaking refrigerant, especially 1234yf, can be an expensive problem. Using a 5% hydrogen/ 95% nitrogen tracer gas mix can help find leaks faster for repair and recharge of the A/C system, without losing refrigerant. The Robinair Tracer Gas service kit gives technicians the tools necessary to use tracer gas in place of refrigerant to find A/C system leaks. The LD9-TGKIT includes a hydrogen gas leak detector with sensor technology designed to detect a 5% hydrogen / 95% nitrogen tracer gas mixture. 

The new Robinair LD9-TG is a tracer gas leak detector with sweep and graph modes to help locate tracer gas fast. 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. Filling a system with tracer gas in place of valuable refrigerant is inexpensive and can help locate leaks faster.

The LD9-TGKIT includes the leak detector, 134a and 1234yf couplers, hose and regulator for tracer gas. Tracer gas sold separately. The leak detectors meet J2970 industry standards for detection and use a patented 3-LED inspection light to help locate and inspect suspected leaks.

Using tracer gas eliminates the need to use expensive refrigerant to find leaks. Filling a system with tracer gas is fast and effective, with a much lower cost than refrigerant.

Detects leaks as small as 0.05 ounces/year for R134a and .015 ounces/year for R1234yf.

The kit includes the LD9 tracer gas leak detector, 134a and 1234yf couplers, hose and regulator for tracer gas.
