Measurement Data Presentation with our #177 Software:
In general are all data stored on the integrated 80 Kb memory, but with the use of the removable data logger card it is possible to store data up to 6 MB in the unit at all times. Even the instrument performance as well as (optional) sensor data are stored on the same card. These results can be called off simply by attachment of any PC and the use of the GRIMM Software #177.
As mentioned in the specification only with one GRIMM instrument it is possible to obtain many different results. As an example below are the data obtained as a single particle counter. The GRIMM Software #177 shows the count and size distribution in ambient atmosphere.
It is also possible to show the mass distribution in many different size channels mass as well.
As a typical application the unit is used at a work place study with the EN 481 it is possible to use the same instrument. Three important fractions as mass by volume over time are shown.
Even the atmospheric aerosol values used in the environmental data base such as PM10 and PM2.5 and even PM1 can be shown . Three PM fractions as mass by volume over time are shown.
