LaserDust™ MP, LP and XLP Monitors


LaserDust  Medium i Long Path (MP-LP)

NEO Monitors 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 LaserDustTM 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.
