Its 128×160 color display offers two detection views — a changing bar graph and a sweep line graph — to help you gauge leak strength and trace the source. Lightweight and battery-powered, the LD7 also includes ultraviolet LEDs for dye inspection and an inspection lamp for low-light work.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the LD7 show leak size so I can find the source faster?\u003c\/h3\u003e\n\u003cp\u003eThe LD7 offers two complementary display modes to communicate refrigerant levels instantly. Bar graph mode changes color as concentrations increase so you can see relative strength at a glance, while Sweep mode plots a line graph to help you follow peaks and move back and forth until the leak is pinpointed.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBar graph color transitions indicate increasing refrigerant concentration\u003c\/li\u003e\n  \u003cli\u003eSweep line graph helps locate leak with back-and-forth tracing\u003c\/li\u003e\n  \u003cli\u003eAudible alarm provides immediate notification when refrigerant is detected\u003c\/li\u003e\n  \u003cli\u003eVisual probe LED shows detection at the sensor tip for precision\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat refrigerants and sensitivity levels does the LD7 support?\u003c\/h3\u003e\n\u003cp\u003eThe LD7 is compatible with the most commonly used automotive and light‑commercial refrigerants, including R‑134a and R‑1234yf.
