Abstract: An improved sensor support subassembly (10) for a chemical sensor (12) in the testing of gaseous emissions. The sensor subassembly (10) includes a sensor unit (12) slidably engaged with a gas intake manifold block (40). The sensor unit (12) has a cylindrical base (20) which forms the sensor inlet (26). The manifold block (40) includes a gas intake (46), a gas channel (42), and a U-shaped slot (50, 50a) for slidably engaging the cylindrical base (20) within the manifold block (40) to form an air-tight passage between the sensor inlet (26) and the gas channel (42). The sensor subassembly (10) also includes a sealing ring (34) for insuring an air-tight seal between the sensor unit (12) and manifold block (40). This allows the sensor unit (12) to be rotated about the axis of the cylindrical base (20) and use of a card-edge connector (16).
