تفاصيل المنتج
Met One BC1054 Black Carbon Analyzer
The Met One BC1054 Multi-spectrum Black Carbon Analyzer by Met One Instruments, powered by Acoem, continuously monitors the light transmittance through filter media where particulate matter gathers. It calculates the black-carbon (BC) concentrations in real-time across 10 different wavelengths, spanning from near-UV to near-IR.
Utilizing the same widely accepted calibration constants and operational principles as industry-standard reference monitors, the BC-1054 delivers black carbon (BC) data with equivalent accuracy and precision, but at a significantly lower cost.
Met One BC1054 Key Features
- Active flow control at either 2 LPM or 5 LPM
- Built-in filter loading correction algorithm
- Internal flash storage of greater than one year's worth of data
- Advanced diagnostics for flow, optics, and tape drive operation
- Ultra-high sensitivity with lower limits of detection less than 1 ng/m3
- Factory calibrated with smoke chamber methodology utilized on
- Met One's time-tested beta attenuation mass (BAM) monitors
