The Model 3031 Ultra-Fine Particle Monitor is specially designed for long-term air quality monitoring networks. It operates continuously for months 24 hours a day with minimal maintenance and does not require any working fluids. The ultra-fine particle monitor has no radioactive source; therefore, there are no special requirements for its licensing, nor restrictions on its use or on the place of its installation. Model 3031 mounts in a standard cabinet in a 19-inch rack; making it easy to install in existing roadside and city air quality monitoring stations. For laboratory or mobile applications, a benchtop version of this instrument (model 031-1) is available.
