The Magee Scientific SootScanâ„¢ Model OT21 Optical Transmissometer bench top analyzer has been developed as a simple and robust way of assessing Black Carbon particulate matter (PM) from a variety of sample filters. The analysis can be easily performed in the field or the laboratory, and requires less than thirty seconds to provide optical attenuation and BC mass concentration results. This non-destructive analysis method requires no support gases or consumables. A neutral density photometric standard filter kit is available for verifying instrument calibration and validating the instrument response.

SPESIFICATION :

* Sample Collection Area

Sample is collected on a defined spot on the filter fiber tape.
Options: ‘High Sensitivity’ option provides a small,
concentrating spot for optimal performance at locations
of low concentration.
‘Extended Range’ option provides a larger, dispersing spot for optimal performance in areas of high concentration.

* Data Output

Digital data is transmitted from rear COM port. Analog output connector represents BC data as 0~5 volt DC signal, scalable in software.

* Data Recording

Data are written to recording medium once every timebase period.
- Option :
Flash memory drive is standard.
Floppy disk may be substituted.

* Consumables Required

Filter tape (sample): 1 to 4 rolls per year, depending on concentrations, and cartridge fi lters (bypass fl ow; internal purge fl ow; fl ow meter protection): approximately one per
year, each.

*Periodic Maintenance

We recommend a fl ow rate verifi cation every three months,
and cleaning the inlet assembly once per year.

*Reliability

Aethalometers have been operating at hundreds of urban,
regional, rural and remote locations on all continents,
continuously since 1986.

*Size

Instrument constructed in portable cabinet with carrying
handle: 11� high, 12� deep, 8� wide.
