GENERAL INFORMATION
“Particulate matter” (PM) is the general term used to
describe solid particles and liquid droplets found in
the air. The PM2.5 series of transmitters are designed
to detect particles less than 2.5 µm in diameter
include smoke, smog, bacteria, fine dust and liquid
droplets, and report the particle concentration of the
monitored environment. The unit utilizes a laser
particulate matter sensor to detect particle sizes
from 0.3 ~ 2.5 µm. The sensor has good long-term
stability with an accuracy 10% reading or 10 µg/m3.
The room unit features field selectable outputs, 4-20
mA, 0-10 VDC, and Modbus RTU (RS485), relay, and
display.
The sensor has two jumper selectable working
modes for monitoring PM. The Normal Mode
monitors the environment continuously and Auto
Mode reduces the measuring time to extend service
life. The sensor default is set to Auto Mode.
IMPORTANT PRECAUTIONS
• This product uses a laser particulate matter
sensor. It is strictly prohibited to be
disassembled. It is dangerous if the human
body is exposed to the laser directly.
• If the environment exceeds the measurement
range for an extended period, it may lead to a
decrease of the measurement accuracy.
• The performance of the sensor may be
decreased due to excessive dust and oil mist,
etc. in extreme environments. (ie: high
humidity, high temperature)
• Avoid strong light into the housing.
• Avoid vibration.
MOUNTING INSTRUCTIONS
For optimal temperature readings, follow these
tips:
• Avoid air registers, diffusers, vents, and
windows
• Avoid confined areas such as shelves, closed
cabinets, closets, and behind curtains.

• Eliminate and seal all wall and conduit
penetrations. Air migration from wall
cavities may alter readings.
• Do not install near heat sources. eg:
lamps, radiators, direct sunlight,
copiers, chimney walls, walls concealing
hot-water pipes
