Product catalog summary

Overview: The laser gas analyzer utilizes TDLAS technology and long-path reflection technology to enhance detection limits significantly. It is capable of analyzing gases such as O₂, CO, NH₃, CO₂, CH₄, H₂O, HCl, and HF, providing a solution for online measurement of trace gases in industries like natural gas, petrochemicals, environmental protection, and steel.

System Composition: The system comprises a transmitter, receiver, and display panel. The transmitter emits a laser through the gas cell, and the receiver processes the signal to calculate gas concentration. The display unit shows results and allows parameter settings with a magnetic pen.

Features:

Multi-reflection technology extends the optical path up to 25m, enhancing detection limits.

Catalog excerpts

GA-5000 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 GA-5000 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
