AFCU-360M

Function Control Unit with Mass Flow Controllers

The AFCU-360M operates as an accurate function control unit for several analyzers of one immission measuring station. The periodical, adjustable tests consisting of one zero point and one defined span point can be done for every component. To prepare fixed span gas concentrations the unit uses technologies like dilution, permeation, UV irradiation or Gas Phase Titration.

Manufacturing Company: HORIBA (Austria) GmbH
  • In cause of the universal use of one zero gas mass flow controller,it is possible to operate several spangas channels only one after the other. 
  • More accurate function control unit as the AFCU-360 in cause of usage mass flow controllers
  • Additional indication of flow rate
  • Comfortable mode selection by rotary switch on front panel, including LED indication of actual mode
  • Operation externally from analyzer
  • Modular Layout enables later upgrade with additional span gas channels

Air Quality Monitoring
Air Quality Monitoring
During the period of rapid economic growth, Japan was burdened with various types of pollution such as water contamination and air pollution. The first step to regain the glow of the sky and the purity of water was analysis. HORIBA's measuring instruments play an active part in various fields to determine, for example, whether established regulations are complied with or whether the air and water are purified properly. The beautiful environment is the world's asset. Going forward, HORIBA will continue contributing to preserving the global environment through measurement.
