Model C-380 helps users detect and pinpoint small leaks of refrigerant gases, including HFC, HCFC, CFC, SF6, R134a and R123. An increasing-tick-rate alarm sounds as a leak is found, and the red indication light flashes more rapidly. The flexible gooseneck probe works in hard-to-reach areas. It can be used in small-scale process cooling refrigeration systems and quality-control environments.
