GRIMM Model 1371 MiniWRAS Portable Nanoparticle & Dust Monitor

Brand: Durag

The compact Wide Range Aerosol Spectrometer (MiniWRAS) is used by many reputable organizations throughout the world. 

This is the only portable instrument on the market that allows simultaneous and precise Real Time Monitoring of Both, Dust and Nano Particles. 

Designed and specifically built for indoor air quality monitoring, the MiniWRAS is a "fit for purpose" state-of-the-art system that combines optical and electrical particle detection in one device.
Features
  • Ultra-wide size range from 10 nm to 35 mm
  • Versatile data acquisition and communication (Bluetooth, USB, RS-232)
  • Real-time counting and classifying of nano and dust particles in one system
  • PM10, PM2.5, PM1 and particle size distribution, particle surface, and dust mass
  • High precision over 41 size channels
  • Self-test for all optical and pneumatic components ensures high quality standards
  • Internal rinsing air protects the laser and detector in the optical cell
  • Optional sensor for temperature and relative humidity
  • Easy to use with GRIMM-Software (wireless)
  • 7 size channels for nanoparticles < 100 nm, 19 size channels for submicron particles < 1 µm
  • Total inlet volume (1.2 liter/min) is analyzed with optical cell and electrical sensors
