The Grimm Model 1.108 Spectrometer/Dust Monitor provides particulate measurement by 90-degree laser light scattering
The Grimm Model 1.108 Spectrometer/Dust Monitor provides particulate measurement by 90-degree laser light scattering. Air with multiple particle sizes pass through a flat laser beam, produced by an ultra-low maintenance laser diode. The scattered signals are detected by a high-speed photo diode and processed by a 15-channel pulse height analyzer for size classification.
The particle counts from the channels are sent to the LCD digital display every six seconds for user viewing. The data is converted into mass distribution and can be expressed in accordance to EPA or occupational health conventions in real time.
