DSL-340 MkIII Double Pass Dust Monitor

The DSL-340 MkIII is an optical double-pass dust monitoring system designed for continuous measurement of particulate concentration in industrial exhaust gases, ducts, stacks, and filtration systems. Using Dynamic Detection Principle (DDP), it provides highly stable dust monitoring with reduced drift, improved reliability, and accurate mg/m³ readings when calibrated. DDP technology minimizes signal drift caused by temperature, contamination, or optical degradation. It provides precise dust concentration monitoring with ±2% accuracy and is built with stainless steel construction for demanding industrial environments. Supports analogue, USB, and Modbus communication for easy system integration. No moving parts and accessible optical surfaces simplify routine servicing. Meets US EPA PS-11 and EU regulatory standards.
