AO2000-LS25 | ABB In-Situ Laser Gas Analyzer Module for Advance Optima
The ABB AO2000-LS25 is an in-situ laser gas analyzer module belonging to the ABB Advance Optima AO2000 integrated analyzer system. It is designed for continuous, real-time measurement of single-component gas concentrations across flues, ducts, or process pipes without requiring a full extractive sampling system.
The module uses tunable diode laser absorption spectroscopy (TDLAS) technology. A transmitter unit and receiver unit are installed opposite each other, and the laser beam passes through the gas stream to measure the average gas concentration along the optical path. The analyzer can provide analog outputs such as 4–20 mA, and may support HART and Ethernet communication depending on configuration.
- In-situ laser gas analysis for cross-duct or cross-pipe installation
- TDLAS measurement principle for selective single-component gas measurement
- No extractive sampling system required in typical in-situ applications
- Fast response suitable for process and emission monitoring
- Analog output support, typically 4–20 mA, for DCS/PLC integration
- HART and Ethernet communication available, subject to configuration
- IP66-rated transmitter/receiver units for harsh industrial environments
- Suitable for ABB Advance Optima AO2000 systems
- Flue gas emission monitoring
- Boiler combustion optimization
- Process gas concentration measurement
- Chemical, petrochemical, and power plant applications
- Cement, metallurgy, and environmental monitoring systems
- Retrofit and spare-part replacement for AO2000 analyzer systems

No. The AO2000-LS25 is primarily an in-situ laser gas analyzer module for the ABB Advance Optima AO2000 system. Some third-party listings may incorrectly describe it as a general analog output module.
It can measure single-component gases depending on configuration, such as O₂, CO, CO₂, NH₃, HCl, HF, H₂S, NO, NO₂, and H₂O. The exact range must be confirmed with the nameplate or datasheet.
In typical in-situ applications, it does not require an extractive sampling system. Purge air may be required to keep the optical windows clean.
We can provide available product information upon request. For official specifications, always refer to the ABB datasheet or authorized documentation.
