IP66 transmitter/receiver units suit harsh environments; 4–20mA, HART/Ethernet outputs enable easy DCS/PLC integration. Ideal for flue gas, combustion and process monitoring. Verify order code and gas range via nameplate.
Product Description
Product Overview

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.

Important: Because "AO2000 LS25" may also be mislabeled as a general analog output module on some third-party listings, the exact order code, measured gas component, range, certification, and supply voltage must be verified with the product nameplate or official ABB documentation before purchase.

Key Features
  • 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

Typical Applications
  • 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

Frequently Asked Questions
Is the AO2000-LS25 an analog output module?

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.

What gases can the AO2000-LS25 measure?

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.

Does it require a sampling system?

In typical in-situ applications, it does not require an extractive sampling system. Purge air may be required to keep the optical windows clean.

Do you provide datasheets?

We can provide available product information upon request. For official specifications, always refer to the ABB datasheet or authorized documentation.
