Carbon monoxide (CO) is typically measured with electrochemical sensing cells: The drawing of air into the sensing cell, the chemical reaction and signal transmission results in a delay in the logging of the actual CO concentration. At times, it is important to be able to accurately record the timing of changing CO concentration, which requires correction for the delay, or time-lag. The aim of this study was to quantify the time-scale of response of LASCAR EL-USB-CO monitors while CO concentrations were increasing and decreasing. We found that it is possible to reconstruct the real CO concentrations from the measured CO concentrations.
