Duct mounting

Although the Net Safety Monitoring Air Particle Monitor has been proven to detect
particulate matter travelling at speeds of up to 20 meters per second (65.62 feet per
second)the detector is virtually unaffected by the velocity of particulate and air that it is
exposed to. Based on the application and the speed of the particulate matter, you can
perform a zero and adjust the sensitivity settings to suit the application.
Net Safety Monitoring recommends the APM be used with the UDM-001 or UDM-002
sample draw system to acquire a cross-sectional sample of air and particulate moving
through ducts. The sample is drawn through perforations along the inlet pipe into a
chamber where the APM is mounted. Particulate matter from the outlet pipe is then
returned to the duct. Refer to
(MAN-0116) for more information.
