Laser Gas Analyzer (Extractive Model) LGA-4500

The Process Gas Laser Analysis System of LGA-4500 series (Extractive Model), the extractive process gas analysis product based on the technology of diode absorption spectroscopy (DLAS), is able to make on-line analysis on carious process gases with high dust or high pressure after the extractive treatment and is with such features as strong adaptability and high reliability.

Product Features

• Laser extractive measurement, high measurement accuracy, strong anti-interference ability
• Optical non-contact detection, with the ability to direct measure gas with high temperature and strong corrosion
• Simple and reliable extractive treatment equipment, with the possibility to be directly installed at the process pipeline
• While system explosion-proof, supporting the automatic compensation of gas temperature and pressure
