Zetian - Model PGA-3000 -Process Gas Analyzer
The PGA-3000 is a newly developed process gas analyzer designed for non-explosion-proof environments requiring multi-component and multi-range measurements. It offers flexible configuration of measurement modules based on on-site requirements. Integrated modules include laser gas analysis, thermal conductivity gas analysis, infrared gas analvsis, electrochemical oxveen analvsis, and ultraviolet gas analysis. These modules enable detection of gases such as O2, CO, CO2, CH4, SO2, NO. and H2 covering both high and trace concentration ranges.
Based on Tunable Diode Laser Absorption Spectroscopy (TDLAS), the PGA-3000 measures gases like O2, CO, and CO2.

- Universal Structure for Easy Integration
Uses a standard 19-inch 4U rack-mounted chassis with modular design of key internal components. - Multi-parameter Integration with Fast Response
Internal modules based on different principles support both high and trace concentration measurements. Gas components are customizable, with fast response and high sensitivity. - High Reliability of Core Modules
Core components such as light sources are imported or designed for high reliability. No moving parts, minimizing impact from vibration or shock.
