We propose an experiment to identify the topological order of the nu = 5/2 state through a measurement of the electric conductance of a mesoscopic device. Our setup is based on interfacing nu = 2, 5/2, and 3 in the same device. Its conductance can unambiguously establish or rule out the particle-hole symmetric Pfaffian topological order, which is supported by recent thermal measurements. Additionally, it distinguishes between the Moore-Read and anti-Pfaffian topological orders, which are favored by numerical calculations.
