Product Overview
LT-3001 Series Flue Gas Analyzer
Industrial-Grade CEMS for Fixed Pollution Sources · UV-DOAS Technology · Real-Time SO₂/NO/NO₂ Monitoring
The LT-3001 Series Flue Gas Analyzer is a professional online continuous emission monitoring system (CEMS) designed for high-emission industries, including power generation, petrochemicals, metallurgy, cement, and waste incineration.
Based on advanced Ultraviolet Differential Optical Absorption Spectroscopy (UV-DOAS), it delivers real-time or offline measurement of key pollutants-SO₂, NO, and NO₂-along with critical flue gas parameters, even in high-humidity, high-dust, and multi-component environments.
As a core tool for implementing China's Air Pollution Prevention and Control Regulations, this system not only ensures enterprises meet emission limits and pass environmental acceptance inspections, but also provides high-fidelity data to support:
- Boiler combustion optimization
- FGD/SCR system commissioning
- VOCs abatement efficiency evaluation
It is certified for deployment at all types of fixed-source emission points, including:
✅ Power plant boilers & industrial kilns
✅ Metallurgical furnaces & cement rotary kilns
✅ Outlet of desulfurization/denitrification (FGD/SCR) systems
✅ VOCs treatment facility exhaust stacks

FAQ
Q1: What gases can it measure, and can the range be adjusted?
A1: Standard configuration measures SO₂, NO, and NO₂. Default range: 0–50 mg/m³, but fully customizable for high-sulfur coal boilers, low-NOₓ burners, or other specific applications to ensure optimal accuracy.
Q2: How does it ensure long-term accuracy and stability?
A2: The system uses UV-DOAS spectroscopy, imported UV source/sensors, and a high-temperature optical path-minimizing drift and interference. Performance specs: accuracy, repeatability, and drift all ≤±2% F.S., with 0.01 mg/m³ resolution.
Q3: Can data be sent directly to government environmental platforms?
A3: Yes. It fully complies with HJ/T 212-2017 and supports direct integration with national/provincial/municipal monitoring networks via RS-485, 4–20 mA, or digital interfaces-no gateway needed.
Q4: Can it operate in extreme temperatures or explosive areas?
A4: Standard operating range: –10°C to +55°C. With optional thermal insulation or explosion-proof housing, it can be deployed in harsh or hazardous zones (e.g., refineries, chemical plants). Two models available: standard and Ex d explosion-proof.
Q5: What is the data storage capacity, and can I set the logging interval?
A5: Onboard memory stores ≥300,000 data points. Users can customize the sampling interval (e.g., every 1 second for process tuning, or every hour for compliance reporting)-flexible for both engineering and regulatory needs.
