The table below lists the time required to obtain readings of 66%, and
90%, of an instantaneous exposure to various gasses. The times listed are for
the sensor only, and do not include the travel time through the wand or
tubing, or digital damping by the device. They are provided only for
estimating the sampling period required for a representative reading.
