German GRIMM 1.109 portable aerosol particle size spectrometer

1) Instrument Description
The GRIMM-1.109 portable aerosol particle size spectrometer is equipped with a built-in pulse free sampling pump, built-in data storage, mobile data storage card, and a large LCD display screen, all controlled by a microprocessor. By adopting the "dual element" technology, real-time analysis of the particle size and mass distribution of inhalable substances can be carried out. The measurement range is 1-65000 μ g/m3. In addition, the instrument can also achieve continuous measurement of particulate matter by the same user in more than 30 particle size channels, and aerosol samples can be collected using a Ø 47mm filter membrane.

2) Instrument application
Research on Basic Aerosols
Characterization of Environmental Aerosol Particles
Workplace testing
Occupational Health Research
Ventilation filter material control
environmental monitoring

3) Instrument features
Compact and portable
It can measure the particle quantity and mass concentration in real time, and the sample can be collected simultaneously using a Ø 47mm filter membrane, followed by weighing or chemical analysis (dual element technology)
Online measurement and data storage through data cards
The data can be displayed in units of μ g/m3 or particle number/milliliter in different particle size channels
Powerful software support
Can be connected to other sensors such as temperature, relative humidity, wind speed, etc PAHs、 Coal smoke, dust particles, etc
