Abstract: A method of making a measuring instrument, such as a gas analyser (20), comprises the steps of: selecting one or more measuring devices, such as an electrochemical cell (9) and/or an infrared gas analyser (14), from a group of measuring devices; selecting a tubular profile (5) of the appropriate length for the selected measuring devices; and mounting the selected measuring devices (9, 14) in the tubular profile (5).
