Zetian/laser gas analzyer/TDLAS/flameproof/LGT-200/environmental/petrochemicals/steel/ - 1

LGT-200 laser gas analyzer uses TDLAS technology and long-path reflection technology, which greatly improves the detection limit. It can analyze O 2, CO, NH 3, CO 2, CH 4, H 2O, HCl, HF, etc, providing a new solution of online measurement of trace gases for natural gas, petrochemicals, environmental protection and steel and other industries. System Composition LGT-200 consists of transmitter, receiver and display panel. The transmitter drives the tunable diode to emit laser of certain wavelengths, which passes through the gas cell, then reaches the receiver. The receiver performs signal processing to obtain second harmonic signal, then calculates the concentration base on the relationship between the second harmonic signal and the gas concentration. The display unit not only shows the measuring results, but also realizes loading and setting of parameters with magnetic pen. High reflectivity mirror Long light path absorption pool Gas inlet Sampling pretreatment system Photoelectric detector High reflectivity mirror Signal control and processing circuit line spectrum" technology, free from interference of background gas. Multi-reflection technology achieves optical path up to 25m, improving detection limit greatly. Integrated flame-proof design, high reliability and stability. Innovative Hall button design, better than infrared key way. Optical path length can be adjusted, measurement range covers constant to trace. Optical non-contact measurement, small drift. Auto Rectification The TDLAS technology combined with long optical path technology, improve the level of detection limit Second harmonic auto rectification function improves accuracy Drift Automatic skew detection
