Abstract
An electrochemical gas sensor assembly comprises an electrochemical gas sensor (1) including sensing (39) and counter (32) electrodes, an intervening body of electrolyte contacting the electrodes, and means (5) for controlling the diffusion of gas to the sensing electrode. A test gas generator (7) is connected to the sensor so as to supply a test gas directly to the sensing electrode (39) by-passing the gas diffusion control means (5).
