Description
The Grimm MINIWRAS 1371 is the only portable battery powered instrument of its type in the world that allows simultaneous and precise real-time monitoring of both micron sized and nano sized particles from 10nm to 35um. Designed for indoor air quality monitoring, occupational health and safety studies and many other applications. The instrument incorporates 2 well known and widely used measurement technologies in the one compact instrument (optical particle counting & diffusion charging).
The Grimm MINIWRAS 1371 simultaneously measures PM1, PM2.5, PM10 in addition to inhalable, thoracic and respirable dust fractions, while also measuring the particle number concentration and particle size distribution over 41 high resolution particle size channels. Using its internal smart lithium-ion battery the Grimm MINIWRAS may be used for up to 10 hours in the field.
