Dust Monitoring Function
The BI 7010 Dual Pass Transmissometer Dust Monitor is an in-situ optical instrument designed to measure dust and particulate concentration in industrial stacks and exhaust flue gas systems.
Measurement Technology
It uses dual-pass light attenuation technology, where a green LED beam passes across the stack and returns via a reflector to measure dust concentration accurately in mg/m³, mg/Nm³, or % opacity.
Industrial Durability
The rugged stainless-steel, no-moving-parts design ensures reliable, low-maintenance operation in harsh industrial environments.
Optics Protection System
An air purge system prevents dust buildup on optics, ensuring stable and accurate measurements over time.
