Laser Gas Analyzers(Compact Model) LGA-3500 -Image

LGA-3500 Series Semiconductor Laser Gas Analyzer, based upon the laser absorption spectroscopy (DLAS) and DSP digital technique, is a new-generation product with high value for money. It carries forward the unique tradition of DLAS technique and adopts the integrated design with small size, stability and reliability.

LGA-3500 (Compact Model)can perform under such conditions as high temperature, high pressure, high dust volume and strong corrosion, and conduct online monitoring of gas concentration in industrial processes. It is widely used in such areas as chemical engineering, concrete, environment protection and metallurgy and provides the best solutions of the industry in view of all kinds of working conditions.

Product features

  • LGA-3500(Compact Model) takes semiconductor with stability and low noise as its light source and adopts
  • Wide application for many different conditions
  • High system stability and little need for maintenance
  • Whole system anti-explosion

System Composition

LGA-3500 Series Semiconductor Laser Gas Analyzer consists of measuring unit and measuring probe etc. Laser light emitted by measuring unit passes through the gas compartment of measuring probe, and is received by the receiver in the measuring unit; after spectra data analysis, it is then displayed on the computer-human interface.
