The CEL-712 Microdust Pro from
Casella CEL is a handheld, data
logging instrument for real-time
detection of airborne dusts,
fumes and aerosols. The
company believes it to have
the highest measurement
range of any device of its
kind currently on the
market. A special filter
enables on-site calibration.

Suitable for occupational health
monitoring as well as industrial
process monitoring, testing air
filtration efficiency, site boundary
monitoring, environmental
measurement and research activities,
CEL-712 Microdust Pro is designed
for harsh environments. It can also
be used for spot checks and walkthrough
surveys of ambient and
indoor facilities. It has a large
display, colour-coded screens, and
a graphical facility, and gives
immediate details of when/where
excessive dust is occurring.

The device comes calibrated to
internationally recognised
‘standard’ dust; by using an optional
TUFF Air Sampling Pump and
gravimetric adaptor, user-defined
dust-type settings may be obtained.
