DV3000
DUVAS DV3000 UV Multi-Gas Analyzer

The DV3000 is a vehicle-based ultraviolet (UV) gas analyzer manufactured by Duvas Technologies. It uses UV (~100-400 nm) absorption spectroscopy for real-time detection of various trace species such as ozone (O3), nitrogen dioxide (NO2), formaldehyde (CH2O), sulfur dioxide (SO2), and nitric oxide (NO). It has a measurement range of up to 1000 ppb for NO2 and O3 and up to 500 ppb for other gas species. It has a detection resolution of 0.1 ppb and a typical time response of 1 second. The DV3000 is equipped on the Environmental Protection Agency (EPA) Geospatial Measurement of Air Pollution (GMAP) mobile platform for air quality monitoring.
