Air Quality and Dust Monitor

摘要

Unitec (Italy] has further upgraded its field-proven microprocessor-based air quality monitor ETL3OOO, by adding an optional light scattering particulate module, PM1 O-LS, and providing the measuring system with new VPN functionalities achieved by means of a multi standard GPRS/EDGE/3G router. ETL3OOO is equipped with up to 5 SENS3000 Plug&Play cells, each one specifically designed for monitoring CO, NO_2, C_6H_6, O_3, CH_4, NOX, NH_3, H_2S and SO_2. In addition air temperature, relative humidity and noise can be simultaneously measured. SENS3000 is based on thick-film sensors, a solid state technology which takes advantage of nano-structured Metallic Oxides Semiconductors (MOS technology).
