C-12 Portable Black Carbon Monitor
Experience Unmatched Affordability in Granular-Scale Black Carbon and Brown Carbon Monitoring!
Introducing the C-12 Portable Carbon Monitor from Met One Instruments Powered by Acoem. This innovative and robust device measures and reports airborne Black Carbon (“BC”) and Brown Carbon (“BrC”) concentrations continuously, with a 1-minute time resolution.
The C-12 sensor employs the principle of 2-channel optical attenuation, which involves the attenuation of both 880 nm near-infrared light and 370 nm ultraviolet light. This attenuation occurs through filter media where particulate matter containing black carbon (BC) and brown carbon (BrC) deposits in real-time. A notable feature of the C-12 sensor is its ability to make over 1,000 filter advances per roll of filter tape. This capability allows the sensor to operate unattended for more than two months in certain circumstances.
The C-12 is an industrial-grade device, offering users real-time information, enabling continuous monitoring of the unit’s data. Despite its affordability compared to other commercially available carbon monitors, it is robustly built in the USA, featuring an all-metal weatherproof enclosure. With proper servicing and calibration, users can expect its operating life to exceed ten years.
The C-12 Portable Carbon Monitor is self-contained, eliminating the need for expensive, space- and power-consuming environmental shelters. Its modest sampling rate (1 LPM) allows it to be easily powered by a modestly-sized solar panel in most regions. In its standard configuration, the C-12 includes an AC power adapter.
As a 2-Channel unit, the C-12 enables users to measure and report BC (utilizing 880 nm wavelength illumination) and BrC (utilizing 370 nm wavelength illumination) particulate concentrations with sensitivity better than 70 ng/m3 at 1-minute time intervals.
Equipped with an integrated CCS+ COMET Cloud modem, data is available in real-time on a customized webpage dashboard. The C-12 Portable Carbon Monitor samples total suspended particulate matter (“TSP”). A stand-alone unit, multiple mounting options for the C-12 are available, including optional Tripod or Pole-Mount.
The groundbreaking new C-12 offers a low initial acquisition cost and low ongoing operational costs.
With a standard sampling rate of 1 LPM, the unit may be flow-checked and flow-calibrated using most commercially available flow calibrators. An optional flow calibration system may also be purchased to support operation (we recommend the Swift 6.0). The C-12 employs the same span calibration value (MACS) used by the models BC 1054, BC 1060, BC 1065, and other commercially available tape-based carbon measurement devices (aethalometers) manufactured by Met One Instruments Powered by Acoem.
