HORIBA has over 100,000 CEM systems installed and 30 years of quality and experience. That is the base on which HORIBA’s ENDA-5000 series of stack-gas analysis systems are built. These systems have a small footprint and use cross modulated non-dispersive infrared (NDIR) and magneto-pneumatic detectors that are inherently drift-free. The ENDA-5000 series are superior continuous analysis systems that perform reliably for difficult exhaust gas measurements, when measurement errors cannot be tolerated. This CEM series features a intuitive touch panel that makes every operation available with the touch of a single button. The ENDA-5000 series systems are also designed for ease of maintenance. They are ideal for a variety of uses, including emissions monitoring from steam boilers, refuse incinerators, and electric power generation plants to assure pollution standards are being met.
CH4 and N2O measurement are also available. Please contact us for more information.
