Dust & Opacity Analyzers

Our range

• Dust & Opacity Analyzer (Single Pass) D10.3: combines transmittance with forward scattered light to cover very low to high dust concentrations, with self-alignment.
• Laser Dust & Opacity Analyzer D10.3LS: the laser version of the single-pass design, suited to medium and large particle diameters, with 4–20 mA and RS485 Modbus outputs.
• Dust & Opacity Analyzer (Double Pass) D10.12: green LED sender and multi-angle reflector, with a low range of 0 … 7.5 mg/m³ and a high range of 0 … 1000 mg/m³.
• Backscatter Light Dust Monitor D10.8: a 650 nm laser measures back-scattered light from one side of the stack, 0 … 200 mg/m³, with in-situ zero and span calibration.
• Extractive Dust Monitor DM10.14E: heat-traced laser forward scattering with isokinetic pitot sampling and a 0.05 mg/m³ detection limit, built for wet, high-humidity flue gas.
• Triboelectric Dust Monitor DM11: a probe that detects particles from 0.1 to 200 µm at up to 1000 mg/m³, rated for pressures up to 1 MPa.
• Smoke Density Meter SDM V9: continuous opacity from 0–100% across paths up to 20 m, with automatic daily and hourly exceedance calculation.

Applications

• Solid and gas fuel boilers
• Palm oil mill boiler stacks
• Power plant flues and ducts
• Generator and diesel engine exhausts
• Rubbish incinerators
• Tunnel visibility monitoring

How to choose

• Expected dust range: scattered light and extractive designs for very low levels, transmittance for higher loads.
• Flue gas condition: wet or saturated gas usually calls for a heated extractive monitor.
• Duct access: double-pass and opacity meters span the stack, backscatter and probe types mount on one side.
