LaserGas™ III SP – SIL2-Ready Gas Analyzer for Hazardous Areas
When process safety and reliability are critical, LaserGas™ III SP provides fast and accurate gas measurements directly in the process — even in certified hazardous areas.
LaserGas™ III SP is an in-situ cross-stack gas analyzer based on TDLAS technology, designed for operation in Zone 1 hazardous areas. The system consists of a transmitter and receiver mounted directly across a duct, pipe, or reactor, eliminating the need for extractive sampling systems.
With near-instantaneous response and no cross-interference, it delivers dependable real-time data for safety-critical and emission-related applications.
