Product Overview
The Explosion-Proof Laser Gas Analyzer employs Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology for real-time, online measurement of gas volume concentrations, including O₂, CO, CO₂, H₂S, and CH₄. Equipped with a front-end gas pre-treatment unit, the analyzer effectively handles harsh environments with high moisture and dust content. Its explosion-proof design ensures safe operation in flammable and explosive atmospheres, making it ideal for industrial gas monitoring to guarantee production safety.
Technical Principles
The instrument uses TDLAS technology to measure characteristic absorption lines of target gases. By precisely detecting the absorption spectra, it achieves high-precision, multi-component gas analysis in real time. The integrated pre-treatment system removes water vapor and particulate matter, ensuring stable and reliable measurement results.
Key Features
- TDLAS Technology: High-precision gas measurement with strong anti-interference capability.
- Self-Diagnostics: Continuously monitors sensor status for stable operation.
- High Automation: Minimal maintenance required; suitable for long-term unattended operation.
- Multiple Data Interfaces: Supports various communication protocols for integration with other systems.
