- Trace Cl2 Analysis System


GA-5000 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.

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 settingof parameters with magnetic pen.
