ANOTHER QUALITY PRODUCT FROM MET ONE INSTRUMENTS, INC. contact: sales@metone.com The BC-1050 is a two-channel, continuous, filter-based monitor that simultaneously measures black carbon “BC” and UV-equivalent particulate matter “UVPM”. Measurements are made through the principle of optical absorption. Attenuation of one light source in the near-infrared “NIR” (935 nm) and another in the ultraviolet “UV” (375 nm) are simultaneously monitored across quartz fiber filter onto which particulate matter is being deposited in real time. The attenuation of the NIR source is used to quantify BC; the attenuation of the UV source may be used to quantify UVPM (UV-equivalent particulate matter). The BC-1050 is highly sensitive: the lower limit of detection is approximately 2 ng/m3 (note 1 ng = .001 μg). The minimum time resolution of the BC-1050 is 1-minute, although 5, 10, 15, 30 and 60-minute time resolution is also available. Each BC-1050 includes: 1 BC-1050 Two Channel (935 nm and 375 ...
