The DSL-800 consists of a single Transceiver (TRX) head that is mounted on one side of the stack only. The TRX head emits a beam of laser light into the stack and any light backscattered from suspended particles is detected by the TRX.

Increased particulate density in the stack gas produces an increase in the level of the scattered light. When calibrated against a standard reference measurement, the measured backscattered light can be used to calculate the particulate concentration and present a reading in mg/m3.

Advantage:

• US EPA PS-11 compliant.
• In situ measurement directly in exhaust gas flow
• Measurement reading as mg/m3 (when calibrated against standard reference measurements).
• Laser backscatter method requires no alignment and only a single access port on the stack.
• Rugged 316L stainless steel construction.
• Intelligent analyser with optional DSCU operator interface.
• Plug and socket connectors for ease of installation.
• Automatic Zero and Span checking.
