Work has been conducted to develop a fuel cell instrument for monitoring carbon monoxide in a mine atmosphere. Reliable, efficient gas sampling and electronic control circuitry have been fabricated for use with the fuel cell sensor and intergrated into a device to meet the performance and design specifications for a portable, battery-powered handheld direct indicating gas detector for use underground. The instruments have a meter readout for the range o to 50 ppm and 0 to 250 ppm CO in air. A resettable lamp is used for a danger warning signal.
