The invention discloses a wide-application-range traceability comparison bar for detection of a cigarette filter stick. The traceability comparison bar comprises an outer elastic casing pipe and capsconnected to the two ends of the casing pipe. More than one vent hole is formed in the end surface of each cap. A central pipe is arranged in the outer elastic casing pipe in a sleeving manner; and aventilation channel is formed in the central pipe. Constant-current pipe assemblies are connected to the central pipe and consist of fixed sleeves and constant-current pipes connected to the fixed sleeves; the constant-current pipes are arranged inside the central pipe; and the end surfaces of the fixed sleeves are in contact with the end surface of the central pipe. More than one group of constant-current pipe assemblies is arranged; and capabilities of resistance to suction of the constant-current pipes of the different constant-current pipe assemblies are different. Because more than one group of constant-current pipe assemblies is arranged and capabilities of resistance to suction of the constant-current pipes of the different constant-current pipe assemblies are different, different constant-current pipe assemblies are replaced separately when different cigarette filter sticks are detected, so that the number, sizes and costs of the traceability comparison bar are reduced; and thedetection precision is improved.
