Octoring

Opacity and colorshift PM (particulate matter) measurement instrument. Uses the OPT4048 optical sensor to detect smoke opacity and colorshift, positioned against continuous PM instruments evaluated in the LBNL/HPBA CRADA study. Independently evaluated by LBNL and published as LBNL-2001749 (March 2026).

• Opacity and colorshift measurement, rated for 1,000 hours of operation between cleaning.

• Transmits packet data (opacity, particle size/concentration, extinction, optical depth) for logging and dashboard display
