Specifications include, but are not limited to: a. Air Monitoring sensors provide real time data for particulate matter (PM) including PM1, PM2.5 and PM10 with a range of (0-2,000 ug/m3). Additionally real time data for Carbon monoxide (CO), NO, Nitrous oxide (NO2), Ozone (O3), relative humidity and temperature. systems use a unique combination of Nephelometry& Optical Particle Counting within the device to obtain reliable PM1, PM2.5, PM10 concentrations alongside full, unrestricted access to all raw sensor outputs in real-time. b. Anemometer must be capable of monitoring wind direction and speed (from 0-89 miles per hour) using sonic pulses to detect air movement without any moving parts. c. Equipment must be solar powered with a battery backup system. Minimum 25,600 mAh battery with a 20W solar panel. d. Contractor must provide warranty service or exchange air monitor sensor or accessories within 2 days of notification using expedited shipping methods. Cost of shipping is paid by Contractor
