LGT-200 Flameproof Laser Gas Analyzer

LGT-200 Flameproof Laser Gas Analyzer

Overview

LGT-200 laser gas analyzer uses TDLAS technology and long-path reflection technology, which greatly improves the detection limit. It can analyze O2, CO2, NH3, CO, CH4, H2O, HCl, HF, etc, providing a new solution of online measurement of trace gases for natural gas, petrochemicals, environmental protection and steel, and other industries.

Features Of LGT-200 Flameproof Laser Gas Analyzer


• "Single line spectrum" technology, free from the interference of background gas.
• Multi-reflection technology achieves optical path up to 25m, improving the detection limit greatly.
• Optical path length can be adjusted, measurement range covers constantly to trace.
• Integrated flame-proof design, high reliability, and stability.
• Innovative Hall button design, better than the infrared keyway.
• Optical non-contact measurement, small drift
