LaserDust

LaserDust™ Medium Path (MP), Long Path (LP), and Extra Long Path (XLP) Monitors are compact, optical dust monitors for true continuous in-situ measurement of dust concentration or opacity. 

The monitors are designed for measurement across pipes, stacks, and ducts with typical path lengths of 0.5 – 10 m. LaserDust™ Monitors use a transmitter/receiver configuration to measure the dust concentration along the optical line of sight. Our true non-contact approach is superior to point type dust meters. 

With innovative laser technology the LaserDust™ combines two measurement principles in one instrument. At low dust levels it operates with forward scattered light technology: 

The incident laser light is scattered by dust particles and collected onto a solid-state sensor for dust quantification. This highly sensible mode enables detection limits of < 0.5 mg/Nm3 and is unaffected by dust depositing on the windows. 

At high dust levels the LaserDust™ will measure transmittance or opacity: 

Light absorption by dust particles is captured by a 2nd sensor.
