Digital NDIR Non-Dispersive Infrared Gas Analyzer Non-dispersive IR Gas Tester NDIR Multi-component Gas Test Machine
Digital NDIR Non-Dispersive Infrared Gas Analyzer Non-dispersive IR Gas Tester NDIR Multi-component Gas Test Machine
Production
The LR-G105 infrared gas analyzer is an intelligent industrial online analyzer developed using the NDIR non-dispersive infrared principle combined with new microcomputer technology. The instrument is suitable for use in various non-explosion-proof environments and can analyze and monitor the content of total hydrocarbons, CO, CO2, CH4, and other gases from ppm levels to 99.9% online.
The instrument features upper and lower limit alarms, digital and analog outputs, and customizable measurement ranges based on customer requirements and working conditions, providing cost-effective solutions.
Typical application areas
Petrochemical, steel and metallurgy, power generation, cement, air separation, chemical, pharmaceutical, bio-fermentation, building materials, new materials, and other industries; including but not limited to online analysis and monitoring of CO, CO2, and other gas content in combustion processes, catalytic cracking reactions, various reaction vessels, storage tanks, process pipelines, combustion furnaces, and exhaust gases.
Instrument Features
> Dot matrix LCD display, selectable display units: %, ppm, mg/m³
> Automatic real-time recording of measurement data (≤3000 entries), recorded data displayed in list or curve format
> Arbitrarily settable control points, passive relay output, standard 4-20mA and RS485
> Rich interface options, connectable to DCS and for communication with computers
> Gas path and program design with sensor sealed protection, ensuring stable overall performance
> High cost-effectiveness; the core sensor uses imported products to ensure accurate analysis results, while other components use domestic parts of comparable quality to imported products, significantly reducing the overall price compared to imported instruments.
