Abstract: A gas sensor instrument comprises a housing formed of two parts (102, 10) and a diffusion chamber inside the housing. The diffusion chamber is formed from two parts (106, 108) and at least one of the diffusion chamber parts is formed integrally with one of the housing parts. This allows a reduction in size of the instrument without compromising the size of the diffusion chamber. Additionally, a tubular projection is formed integrally with one of the housing parts to form part of a Faraday cage for shielding an amplifier circuit of the instrument.
