dimensions of the instrument are shown in Figure 8 - Overall Mounting
Dimensions of the Instrument.
Figure 8 - Overall Mounting Dimensions of the Instrument
Be sure that the instrument is mounted as close as possible to the
sampling point to ensure a quick response time (recommended
installation is within 2-3 meters (6-10 ft) of the sampling point).
Mounting bolt size should not exceed the size of provided mounting
bolt location. Mounting hardware must be rated to support the
instrument operation weight of 60 lbs. Mounting hardware provided
