WT602 is an online laser dust monitor developed for continuous measurement of particulate matter (PM) concentration in industrial stacks, flues, and exhaust ducts.
Based on the laser backscattering principle, WT602 provides stable, real-time dust concentration data for environmental monitoring, emission control, and process optimization.
The instrument adopts single-end installation, does not require optical alignment, and can be directly mounted on chimneys or pipelines. It is widely used in power plants, cement plants, steel works, chemical and petrochemical industries, and can be easily integrated into CEMS, PLC, DCS, or SCADA systems.
WT602 uses a 650nm semiconductor laser (7mW) to emit a modulated beam into the flue gas.
When dust particles pass through the laser beam, scattered light is generated. The backscattered light is collected by a photoelectric sensor and converted into electrical signals.
Through DSP digital signal processing, phase-locked amplification, modulation and demodulation, the system accurately calculates the dust concentration and outputs stable real-time values.
This optical structure effectively avoids errors caused by:
Gas temperature fluctuation
Mechanical vibration
Refractive index changes in flue gas
Laser Backscattering Technology – stable and accurate in harsh industrial environments
Single-End Installation – no optical alignment required
On-Site Display – real-time dust concentration shown directly
Strong Anti-Interference – laser modulation & DSP processing
4–20mA Analog Output – compatible with PLC / DCS systems
RS485 Modbus RTU Communication (optional)
Low Power Consumption – only about 3W
No-Tool Installation Concept – easy maintenance
Purge Air Protection – prevents lens contamination
Offline Zero & Span Calibration with calibration block
WT602 can be used as a standalone monitor or integrated into a CEMS system. It is suitable for:
Power plants
Cement plants
Steel works
Chemical & petrochemical plants
Industrial boilers
Flue gas emission monitoring
Dust removal system process control
Flange mounting on stack or duct
Purge air connection (oil-free, water-free compressed air)
Zero & span calibration recommended every 3–6 months
Optical window cleaning cycle: 3–6 months
Designed for 24/7 continuous operation
