The BC 1054 Multi Spectrum Black Carbon Monitor provides a reliable, cost effective solution for high time resolution data collected at 10 wavelengths ranging from the near-UV to near-IR

The BC 1054 Multi Spectrum Black Carbon Monitor comes standard with active flow control. Utilizing arobust design with a single mass flow controller and a single flow path, the standard configuration permits easy flow calibrations and leak tests. A high-concentration option is available and recommended for use when BC concentrations are expected to exceed 7,000 ng/m3 on a routine basis. The high concentration option extends the time between tape replacement without sacrificing sensitivity.

All BC 1054 Multi Spectrum Black Carbon Monitors are equipped with a humidity control system that may be set to maintain a constant sample temperature and thereby reduce moisture-related measurement artifacts

Applications:
•Air Quality Surveillance
•Global Warming Studies
•Particulate Emissions Studies
•Near-Roadside Monitoring
