Met One- BC 1054 Black Carbon Analyzer

The Met One BC 1054 is a high-precision black carbon analyzer designed for continuous, real-time monitoring of black carbon concentrations in ambient air using multi-wavelength optical absorption technology.

  • Wide Measurement Capability: Accurately measures black carbon from <1 ng/m³ to >100,000 ng/m³, suitable for both low and high pollution environments.
  • High Sensitivity & Resolution: Detects very low concentrations with a limit of detection <8 ng/m³ and 0.1 ng/m³ display resolution.
  • Flexible & Reliable Operation: Mass flow–controlled internal pump (2 or 5 LPM), tape-saving mode, and easy flow checks for dependable long-term monitoring.
  • Advanced Data Handling: Supports USB, RS-232, and Ethernet, with optional cloud access for remote, near real-time data retrieval.

Description

The Met One BC 1054 is a high-precision black carbon analyzer engineered for continuous, real-time monitoring of black carbon concentrations in ambient air. Using advanced multi-wavelength optical absorption technology, it delivers accurate and stable measurements across an exceptionally wide concentration range, making it suitable for both background air quality studies and heavily polluted urban or industrial environments. Its high sensitivity allows detection of ultra-low black carbon levels, supporting detailed research, regulatory monitoring, and climate-related studies.

Designed for reliable long-term operation, the BC 1054 features a mass flow–controlled internal pump with selectable flow rates, along with a tape-saving mode that reduces maintenance and operating costs. Flexible data communication options including USB, RS-232, Ethernet, and optional cloud connectivity enable seamless integration into monitoring networks and remote data access in near real time. With its robust performance, precise measurement capability, and advanced data handling, the Met One BC 1054 is an ideal solution for environmental monitoring agencies, research institutions, and air quality professionals.

Features

  • Data gathering in high BC zones is done in tape-saving mode to save money.
  • The ability to upload and store gathered data on the Web is provided through an optional cloud-based modem and data service.
  • Without requiring an external data recorder, data may be accessed remotely in close to real time.
  • The straightforward sensor archaitecture uses a single mass flow controller, does not need flow splitting, and works well with filter media.
  • It is easy to carry out flow checks, audits, and troubleshooting.
  • It measures actual flow rates.
