A single-piece adapter (10) is disclosed for supplying gas to a gas detector (32) that contains at least one gas sensor (34) and that has a gas inlet (30) for allowing gas at the inlet to come into contact with the at least one sensor (34), which adapter comprises: chamber (24) having an opening formed by a rim (22) for fitting over the gas inlet of a gas detector (32), the chamber having an inner surface (18), an inlet duct (14) for feeding gas into the chamber in a direction transverse to the opening, and an outlet (16) to vent gases from within the chamber. The inner surface (18) of the chamber is formed by a first moulding (12) of a rigid, non-absorbent material and a second moulding (20) of resilient material. The second moulding forms the rim (22) for providing a gas-tight seal between the adapter (10) and the detector (32).
A single-piece adapter for supplying gas to a gas detector that contains at least one gas sensor and that has a gas inlet for allowing gas at the inlet to come into contact with the at least one sensor, which adapter comprises:
A method of supplying gas to a gas detector that contains at least one gas sensor and that has a gas inlet for allowing gas at the inlet to come into contact with the at least one sensor, which method comprises providing an adapter that comprises a chamber having an opening, a gas inlet duct and an outlet, placing the opening of the adapter over the gas inlet of the gas detector to form a seal between the adapter and the detector to isolate the chamber from the atmosphere, wherein the inner surface of the chamber is formed by a first moulding of a rigid, non-gas absorbent material and a second moulding of resilient material, the second moulding forming the part of the surface surrounding the said opening.
