NDIR Gas Analyzer CO CO2 CH4 CnHm High-Stability Infrared Detectors Process Gas Monitoring
NDIR stands for non-dispersive infrared. It is a type of gas analyzer that is used to measure the concentration of gases in a sample. NDIR gas analyzers are based on the principle of infrared absorption spectroscopy. Infrared radiation is emitted from a source and passed through the sample. The sample absorbs some of the infrared radiation, and the amount of absorption is proportional to the concentration of the gas in the sample. The absorbed infrared radiation is detected by a detector, and the signal from the detector is used to calculate the concentration of the gas.
NDIR gas analyzers are used in a variety of applications, including environmental monitoring, industrial process control, and medical diagnostics. They are available in a variety of sizes and configurations to meet the needs of different applications.
Here are some of the advantages of NDIR gas analyzers:
- They are relatively inexpensive.
- They are easy to use.
- They are accurate and reliable.
- They can measure a wide range of gases.
- They can be used in a variety of environments.
Here are some of the disadvantages of NDIR gas analyzers:
- They can be affected by water vapor and other interferences.
- They can be slow to respond to changes in the concentration of the gas.
- They can be sensitive to temperature and pressure changes.
NDIR gas analyzers are a valuable tool for measuring the concentration of gases in a variety of applications. They are relatively inexpensive, easy to use, and accurate and reliable.
NDIR gas analyzer IR-GAS-600 this model high-stability infrared detectors for simultaneously measuring CO, CO2, and CH4. H2 always reads correctly, independent of the background gas composition. An optional non-depleting paramagnetic sensor can be used to conduct O2 analysis. All sensors/detectors are temperature-controlled or temperature-compensated for maximum analytical stability.
1. Process Gas Monitoring: Well-suited for continuous monitoring of gases in industrial processes, ensuring safety and compliance with environmental regulations.
2. Integration Capabilities: These analyzers can often be integrated into existing control systems or data logging platforms for seamless operation within a larger process.
3. Application Flexibility: Suitable for a wide range of applications including combustion control, emissions monitoring, and process optimization.
Both types of analyzers are available with analysis of:
- Carbon Monoxide (CO) via infrared detector
- Carbon Dioxide (CO2) via infrared detector
- Oxygen (O2) via electrochemical sensor or optional paramagnetic
- Methane (CH4) via infrared detector
