*NOTE 1: Response times are for the instrument without sample lines.
When using a sample line, add time for the gas sample to be drawn through the
sample line. Typical transport times are:
5 feet
10 feet
50 feet
These should be added to the sensor response times reported in this chapter.
**NOTE 2: Extended temperature range indicates that gas readings may vary
slightly if calibrated at room temperature. For optimal performance, it is
recommended that the instrument be calibrated at temperature of use.
