For many years GRIMM has been manufacturing different versions of aerosol spectrometers, which are used frequently in the field. More often than before the question is: Can the smallest particles be detected with these instruments? For the first time, this is now possible.
Two technologies were combined within the new Mini-WRAS (Mini Wide Range Aerosol Spectrometer): (a) the optical aerosol spectrometer and (b) a stepping mode operated electrode with faraday cup electrometer. Thus, the scattering light diameter of 0.20 to 35 micrometers and the diameter of the electrical mobility from 10 to 200 nanometers can be combined in a wide size range. 41 size channels are being measured every minute, ranging from 0.01 up to 35 micrometers and are released continuously.
With a total weight of only 7.6 kg, an integrated battery and advanced data communication interfaces (Bluetooth, USB, Ethernet and RS-232), this aerosol monitor is unique in the world.
• Release of measurement data every minute as particle number in 41 size channels
• Portable, compact and with integrated rechargeable battery and air drying
• Distribution of count and mass or output according to occupational health standards EN 481 (inhalable, thoracic, alveolic) can be indicated via Bluetooth and user-friendly software
• Readout of PM10, PM2.5, and PM1 values is also possible with the software
• Does not need any butanol
• Does not need a radioactive source
