Gas analysis system GasTDL-3110

laser processdatasample

Product overview
GasTDL-3110 is an extractive TDLAS laser gas analysis system for continuous, real-time measurement of a single target gas. Configurable for H2S, O2, CO, CO2 or CH4, the cross‑beam TDLAS design ensures high selectivity and measurement accuracy with minimal interference from background gases.

Design & Operation
The system uses an extractive sampling approach integrating a sampling probe, pretreatment unit, control unit and gas analysis unit. Built-in automatic probe purging, condensate drainage and multi-stage filtration enable stable continuous operation in harsh process environments including high temperature, high humidity, high dust loading, high flow and corrosive atmospheres.

Applications
Designed for process optimization, energy reduction and safety monitoring in industries such as oil & gas, chemical processing and metallurgy. Suitable for continuous process gas and syngas monitoring.

Segment / Division
Segment: Process Gas Analyzer
Division: Syngas Analyzer
