Overview

The ABB EL3040 is a high-performance non-dispersive infrared (NDIR) gas analyzer designed for continuous measurement of various gas components in industrial processes and environmental monitoring.
It provides accurate, stable, and reliable gas concentration readings for components such as CO, CO₂, NO, SO₂, CH₄, and N₂O, supporting a wide range of applications in power generation, petrochemical, metallurgy, and emission monitoring systems.

Functional Features

Advanced Measurement Principle:
Utilizes the Non-Dispersive Infrared (NDIR) measurement technique for precise and stable gas concentration detection.

Multi-Component Detection:
Capable of simultaneously measuring multiple gases including CO, CO₂, NO, SO₂, CH₄, and N₂O.

Flexible Range Selection:
Offers multiple configurable measurement ranges to accommodate various process conditions and concentration levels.

Three Operating Modes:

Manual mode: User-defined range and control.

Automatic mode: Automatic range switching based on gas concentration.

External control mode: Range and measurement control via external signal or system command.

Stable and Reliable Operation:
Designed for continuous, long-term use with minimal drift and maintenance requirements.
