For continuous emission monitoring of complex applications. Simultaneous determination of up to 12 measuring components like HCl, CO, NO, SO2, NO2, N2O, NH3, H2O, CO2, HF, TOC and O2

Continuous Emission Monitoring Solution

World leader in stack gas monitoring systems for more than 40 years and pioneer in FTIR technology, ABB Analytical is offering an inexpensive and forward-looking system with the ACF-NT (former Advance Cemas FTIR) multi-component emission and process monitoring system.


Continuous, quantitative and selective measurement of HCl, HF, H2O, CO, CO2, SO2, NOX, NH3, N2O, O2, TOC and NMHC (other gases on request)

  • Maximum 12 measuring components (standard), simple upgrade on request
  • Proven hot wet extractive measurement technique
  • High stability, accuracy and reliability through proven FTIR technology
  • Fully integrated TOC and O2 analyzer modules (optional) according European Standard EN12619
  • Unique air-driven injector pump, no moving parts, low condensate to handle
  • Low ownership, maintenance and installation cost through multi-component measurement technology with only one sampling system
  • Complete pre-engineered system, modest space requirement, compact and modular system design
  • Clear-text status messages and user-friendly operator interface on a large back-lit display
  • Measured value and status signal transmission via analog and digital outputs and via Modbus or Profibus
  • Remote control and remote maintenance via Ethernet or modem
  • Integration and display of signals from other detectors (e.g. dust, mercury, flow, pressure, temperature)
