A handle having a handle body, a latching arm, and a pivot block is provided. A service-specific probe is an active probe that closely mimics the service traffic so that it receives the same treatment from the network as the actual service traffic. The connection portions 29 are punched out into the region to be filled with the molding material, the connection leads 24 and the electrodes 42 are connected, and the molding material 36 is poured in. The refrigerant in the main flow path is then expanded and heated in the evaporator and enters the compressor, completing the cycle. The apparatus includes an optical resonator disposed within an environment of the thin-film process, a tunable laser that excites the optical resonator at a characteristic frequency of the gas and a detector that detects an energy within the resonator.
