Black Carbon Monitor BCM

The Vair-9017 Black Carbon Monitor from vasthi Instruments delivers accurate, real time black carbon data using at 7 wavelengths Aethalometer technology (UV-IR range)
Designed for advanced research and regulatory monitoring, it enables reliable source apportionment of diesel, biomass and industrial emissions.

Aethalometer Working Priniciple

• continuous aerosol sampling on filter tape
• Multi-wavelength (7 channels) light absorption measurement
• Optical attenuation converted to BC concentration (ng/m3)
• spectral analysis enables source differentiation

Why it Matters

• 7-Wavelength Analysis: High - confidence source apportionment
• Stable Measurements: Intergrated humidity control minimizes error
• Robust Design: Single flow path - easy calibration, low maintenance
• Flexible Integration: Ethernet, RS-485, RS-232,USB
• Optional dilution system supports high BC concentrations(>7,000 ng/m3)_ ensuring accuracy and durability in industrial and urban deployments.

Designed and manufactured for Researchers &
Decision Makers ideal for:

• Atmospheric & climate research
• Long-term monitoring networks
• Government & meteorological departments
• Emission source studies
