LD-3C model laser dust monitor is an
intelligent multifunctional portable
monitor developed by Beijing BINDA
Green Technology Ltd. –the former
Dust Group of Beijing Institute New
Technology Application. Being one
kind of advanced world standard dust
monitor, the monitor can be used to
quickly measure inhalable
particle--PM10-- concentration in
public, measure the labor hygiene
related dust concentration at the
field of production and monitor
inhalable dust concentration in
environmental protection, as well as
evaluate the efficiency of an air
cleaner.
The monitor is a light-scattering
one with a laser light source. The
quality control comes up to the
national technology supervision
ministry’s standard—Light-scattering
Type Digital Dust Monitor Quality
Control Regulations JJG 846-93 and
the operation comes up to the labor
ministry’s standard—Light-scattering
Measurement of the Dust
Concentration in Air LD98-1996 and
hygiene ministry’s
standard—Measurement Method of
Inhalable Particle Concentration
(PM10) in Air in Public,
Light-scattering Method
WS/T206-2001.
