From portable solutions (for mobile and quick measurements) over 19″ rackable solutions (for professional container) up to stand-alone models (for container independent monitoring) and from stations in Amazonas rain wood forest up to Himalaya, from Central Europe deep into the Mongolian dessert and up to airborne measurements, the GRIMM’s environmental dust monitors cover all applications you need. As the pioneer with the first approved system of optical environmental dust monitoring, the GRIMM’s instruments passed until now over 15 equivalence tests worldwide (US EPA, UK MCERT, Germany LUBW, Austria UBA, etc).
