Product catalog summary

Overview
The LGT-180 is a 19" panel-mounted tunable laser gas analyzer designed for industrial online analysis and environmental monitoring. It utilizes TDLAS technology and multiple reflection long optical path technology to analyze various gases such as O₂, CO, NH₃, H₂S, CO₂, CH₄, and H₂O. The system is customizable to meet specific working conditions and can measure gas concentrations from constant levels to trace amounts.

System Composition and Features

Compact structure for easy integration.
Strong anti-interference capability with high precision and minimal drift.
Low detection limit and high sensitivity, adaptable to corrosive environments.

Catalog excerpts

LGT-180 Laser Gas Analyzer LGT-180 is a 19" panel mounted type tunable laser gas analyzer for industrial online analysis and environmental on-line monitoring. The analyzers combine TDLAS technology and multiple reflection long optical path technology that can analysis a variety of gas including O 2, CO, NH 3, H 2S, CO 2, CH 4, H 2O. Reflected light can be customized according to the working condition demand, the measured gas concentration ranges from constants to the trace. System Composition Transmitter, receiver and gas cell are integrated into a 19" 3U chassis. Analyzer can be panel mounted in a 19" cabinet. Sample gas is filtered and dewatered through probe. Then in the gas cell, it is exposed to laser emitted from the transmitter. The receiver calculates the gas concentration from the spectrum received. structure, easy integration 19" standard 3U panel chassis, modular design, easy integration with other instruments. Strong anti-interference capability, high precision, small drift Adopting wavelength-modulation-spectroscopy allows better anti-interference capability of background gas and higher reliability. detection limit, high sensitivity Multi-reflection technology achieves optical path up to 25m, improving detection limit greatly. The sensitivity can reach ppm level or even ppb level for some components. For applications in corrosive environment, all parts of LGT-180 exposed to sample gas are made of corrosion-resistant material. System adopts the sampling measurement method. It can be directly installed in the process pipe to sample, process and analyze, no moving parts, high reliability.
