Quantitech Ltd, has announced that the 'Grimm 180
Environmental Dust Monitor' has been approved for
the measurement of PM10 particulate
matter under the European Standard EN 12341. The Grimm
180 is a continuous ambient fine dust monitor, capable
of providing highly accurate data on PM10,
PM2.5 and PM1.
In order to achieve this approval, the instrument had
to undergo extensive tests - both in the field and in
Field tests involved two units measuring against two reference
units at both urban and rural locations and during both summer
and winter months, in order to check performance during a
variety of climatic conditions.
Dust mass is measured by the orthogonal light scattering
method, which generates count data for each of the particle
size channels and data can be logged internally, displayed
- or transferred to PC, using supplied intuitive software.
