Laser Gas Analyzers – Real-Time In-Situ Process Monitoring with TDLAS Precision
See Your Process Gases Instantly — No Sampling, No Delay
In fast-moving industrial processes, every second matters. Traditional gas analyzers that rely on sampling systems often introduce delays, maintenance burdens, and measurement errors.
The Instrava Curated Laser Gas Analyzers use advanced TDLAS (Tunable Diode Laser Absorption Spectroscopy) to deliver true in-situ, real-time gas measurement—directly inside the process.
No sampling. No pre-treatment. Just accurate, fast, and reliable data when you need it most.

What is a laser gas analyzer and how does TDLAS work?
A laser gas analyzer uses TDLAS technology to measure gas concentration by detecting how specific laser wavelengths are absorbed by target gases. It provides high precision, fast response, and no cross-interference, making it ideal for industrial process monitoring.
What are the advantages of in-situ laser gas analyzers compared to extractive systems?
In-situ analyzers measure gas directly in the process, eliminating:
- Sampling lines
- Gas conditioning systems
- Transport delays
This results in:
- Faster response time
- Lower maintenance cost
- Higher measurement reliability
Can laser gas analyzers operate in high-temperature and dusty environments?
Yes. These analyzers are specifically designed for harsh conditions:
- Probe temperature up to 400°C
- Handles dust concentrations up to 30 g/m³
- Heated optics prevent contamination
They are widely used in cement plants, power plants, and petrochemical processes.
Which gases can be measured with a laser gas analyzer?
Typical measurable gases include:
- O₂ (oxygen)
- CO (carbon monoxide)
- NH₃ (ammonia)
- HCl, HF
- H₂O (moisture)
Custom configurations are available depending on the application.
How accurate and stable are TDLAS gas analyzers?
Laser gas analyzers offer:
- Accuracy up to ±2% F.S.
- Stability of ±0.1% F.S./7 days
- Repeatability of ±1% F.S.
This ensures long-term reliable operation with minimal recalibration.
What industries benefit most from laser gas analyzers?
Laser gas analyzers are widely used in:
- Power generation (boilers, flue gas monitoring)
- Cement & steel industries
- Petrochemical processing
- Waste incineration
- Environmental emission monitoring
They are ideal wherever real-time, high-accuracy gas monitoring is critical.
