German Grimm 11-R Mini LAS Aerosol Particle Size Spectrometer

New Environmental Dust Analyzer, 11-R

Mini LAS Particle Size Spectroscopy

The mini LAS 11-R is a new generation product of Grimm laser particle size spectrometer. *The design of the 11-E, reliable optical measurement technology, and efficient data communication make it a star product in the portable dust measuring instrument market.

Using high-tech laser detection and particle size distribution technology, 11-R uses the principle of single particle measurement to detect the particle size distribution of particles in 31 channels ranging from 0.25 microns to 32 microns in the air.

o Self-test at each start-up

O Self check every time the device is turned on

o Flow and return of the permanent rinsing air for keeping the optical measurement cell clean

Blowing air to avoid contamination of the light detection unit

o Via software: PM10, PM2.5 and PM1 values in real-time

Real time display of PM10, PM2.5, PM1

o Output of measuring data as particle count and output of dust mass fractions in 31 channels

Output particle size distribution data for 31 channels

11-R provides multiple ways to view and store data. Users can conveniently view data remotely through laptops or netbooks, and even remotely through apps. Data can be stored on an SD card or USB.

Grimm has over 30 years of experience in the manufacturing of aerosol measuring instruments. With its light scattering measurement unit and electronic signal processing technology, it uses high-quality materials and components to ensure the precision and data quality of the instruments.

As shown in the flowchart on the left, the sample air enters the detection chamber from the top and is measured in a single particle detection manner (which is different from the principle of turbidity meter). At the beginning of each test, the airflow at the pump outlet passes through the filter and enters the testing chamber as zero gas to calibrate the instrument's zero point.In addition, the 11-R dust analyzer can collect particulate matter onto PTFE filter membranes for subsequent laboratory analysis while measuring.
