Why Optical Gas Analysis is Key to Better Measurement

01

Non-Contact Technology

Optical gas analyzers work without touching the gas. This makes the system safer and protects the parts from damage or wear. It also reduces the need for sample handling equipment.
02

High Selectivity

These systems are built to target specific gases. A Tunable Diode Laser analyzer can detect a single gas, even in a mix of many. This makes the readings more accurate and helps avoid false alarms.
03

Low Maintenance

There are no moving parts, filters, or chemicals. With fewer parts to wear out, you spend less time and money on maintenance. The system stays in service longer, even in tough places.
04

Multi-Gas Detection

The Infrared Gas Analyzer is often used to track several gases at once. This is useful in places like power plants, where gas flows are complex. One system can check for CO₂, CO, CH₄, and other gases.
05

Fast Response

These systems give readings in real-time. If gas levels change, you see it straight away. This helps prevent damage and supports better process control.
06

Regulation Support

Governments and agencies now expect tighter gas controls. Optical analyzers help you follow rules by giving clear, traceable results that meet both local and global standards.

Our Optical Gas Analyzer Solutions

Tunable Diode Laser Absorption Spectroscopy (TDLAS) Analyzer – Built for Precision

Tunable Diode Laser analyzers utilize laser beams to detect specific gases. The laser passes through a sample line or process gas, measuring the amount of light absorbed by the gas. The degree of light absorption indicates the concentration of the gas.

These systems are ideal for low-level gas detection, offering high precision, stability, and quick response times. They are suitable for use in high-temperature, high-pressure, or challenging environments with contaminants.

Features:

  • Real-time gas detection for immediate data
  • Stable over long-term use, minimizing drift
  • No frequent recalibration required
  • Resistant to cross-gas interference, ensuring reliable measurements

Infrared Gas Analyzer – Reliable and Proven

Infrared Gas Analyzers measure gas concentrations based on how gases absorb infrared light. Each gas absorbs light at specific wavelengths, and the system measures the reduction in light intensity to determine gas levels.

This technology is ideal for multi-gas measurement and is commonly used in applications such as emissions control, combustion tuning, and safety monitoring.

Features:

  • Multi-gas capabilities, allowing simultaneous detection of several gases
  • Highly resistant to dirt and moisture, ensuring reliability in tough environments
  • User-friendly calibration and operation
  • Versatile for indoor and outdoor applications

Key Features of Optical Gas Analyzers

Optical gas analyzers offer distinct advantages, making them an ideal choice for various industrial applications. Key features include:

Direct Gas Measurement

Provides real-time readings directly from the gas stream, eliminating the need for sample pumps or tubes.

No Drift

Delivers consistent performance without requiring frequent zeroing or span checks

Digital Output

Seamlessly integrates with control systems such as SCADA and DCS for enhanced process management.

High Sensitivity

Capable of detecting gases at extremely low concentrations, down to parts per million (ppm).

Robust Design

Built to withstand challenging industrial environments, including heat, dust, and vibration.
