LaserGas™ II SP – Robust In-Situ Gas Analysis for Harsh Processes

LaserGas™ II SP is a versatile in-situ gas analyzer designed for reliable measurement in challenging industrial processes — from high temperatures to dusty and corrosive environments.

Based on proven TDLAS cross-stack technology, LaserGas™ II SP measures gas concentration across the full diameter of ducts and stacks. Direct installation on process flanges ensures fast response and eliminates errors associated with gas sampling and conditioning.

The analyzer is certified for hazardous areas and widely used across multiple industries for both process control and emission monitoring.
