Abstract Experiments were conducted by the U.S. Bureau of Mines with six diffusion-type carbon monoxide (CO) sensors to determine their response to a reference CO concentration under both static and dynamic flow conditions. Static experiments were conducted with 0.5 L/min flow of 16 ppm CO in N2 through 8 and 12 liter chambers. Dynamic flow experiments were conducted in two environmental chambers. The results of the static experiments demonstrated that the sensors consistently underestimate the reference gas concentration. The dynamic experiments results showed the sensors provided reasonable agreement with the reference gas concentration when directional flow effects were not considered. Directional flow effects were evaluated for two sensors. The sensors' directional flow effect is significant for their proper in-mine utilization to enhance mine safety through the implementation of a mine fire early warning system.
