        MDA Scientific has developed a sophisticated range of highly sensitive gas detection equipment, designed to perform in ways that define new gas detection performance levels providing total solutions to protect people, improve production efficiency and reduce costs.

        Midas? is a registered trademark of Honeywell Analytics.
        As with all electrochemical sensor cells, dramatic output changes in reported concentrations can be
        expected under rapidly changing environmental conditions. Please ensure sensors are located in areas not
        prone to sudden changes in humidity and temperature.
        Actual readings may be affected by flow rates (although Midas? automatically controls flow rate within
        specified ranges) and absorption on tubing and other gas path surfaces.
        All sensors are shipped pre-calibrated to traceable national standards. Dependent on actual operating
        conditions and overall exposure to gases, each sensor may not require in field calibration for up to 24
        months subject to any requirements to calibrate from local regulations or site practices.
        Calibration and challenge gases should be from a certified and reliable source.
        Cross Sensitivities
        Each Midas? sensor is potentially cross sensitive to other gases and this may cause a gas reading when
        exposed to other gases than those originally designated. The table below presents typical readings that
        will be observed when a new sensor cartridge is exposed to the cross sensitive gas (or a mixture of gases
        containing the cross sensitive species).
