Additional features which are available with the 1.105 and 1.108 models include:

• Particle Counts from 1 to 2.000.000 particles/liter

• Particle Sizing in 8 (or 15) different channels

• Dust Mass Distribution determination

• Filter Efficiency determination

• Sample Collection on 47mm removable Teflon filter.

To insure safer conditions in the workplace international standards pertaining to Indoor-Air-Quality (IAQ) have already been agreed upon. For example, the standard guidelines for the maximal allowable dust concentration conditions during any given 8 hour work period are clearly defined in Europe under EN- 481 and internationally in ISO- 7708. The United States uses AIHA, and Japan the occupational health association both follow these very similar standards.

All GRIMM 1.100 dust monitors are capable of simultaneously measuring in real time, not only the Inhalable dust mass level, they also express the Thoracic and Alveolic dust masses at the same time. All these results can be obtained in parallel with one single unit.

The enhanced aerosol spectrometers from GRIMM are the world’s smallest family of battery operated portable units available on the today’s market. On the left side in the above photo you can see the model 1.108 with its 15 size channel count and mass distribution analyzer, on the right is the standard occupational analyzer and model 1.101 the standard Workplace monitor as outlined above. The 1.108 also have the data storage card along with the CD-ROM containing the GRIMM AEROSOL Software. We also provide you with a black leather carrying case for field use. 

Our world-wide proven portable dust monitors have an internal pulse-free sampling pump, internal data storage, a removable data storage card and large LCD display, all of which, are controlled via microprocessor. The unit can be operated via 9 command key buttons or controlled via PC with our software.

All monitors include our patented dual technology where we first measure the particle size and mass distribution in real time, generated through a scattered laser light, then permitting a validation/correlation by weighing the sampled dust collected on the integrated filter. This post-field correlation allows you to analyze if there is always the monitor functioning as it should.
