DUST AND OPACITY MONITOR
The cost-effective solution for continuous, contactless dust and opacity measurement at medium to high concentrations in dry flue and process gases.
- Non-Contact & Continuous Measurement: Measures dust/opacity in real-time without entering the gas stream
- Auto-Collimation Principle: Light beam traverses measuring path twice (double-pass) for accurate readings
- Automatic Checks: Self-tests zero/reference points and compensates for soiling, reducing maintenance
- Low Maintenance: Durable LED light source and purge air system minimize upkeep
- Versatile Output: Displays in opacity, extinction, or mg/m³; outputs include 4–20 mA, RS485 (Modbus), and relays
- Cost-Effective & Compact: Space-saving, budget-friendly solution for smaller plants or process monitoring
- Robust Housing: Corrosion-free plastic housing for durability
- Emission measurement of dry flue gases at the stack
- Measurement of dry flue gases in the process
- Corrosive flue gases, challenging gas matrix
- Measurement of dry process gases
