                         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 
                          the laboratory.

                  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.
