Over 100,000 systems installed and 30 years of quality and experience. That is the base on which HORIBA's new ENDA–5000 series of stack–gas analysis systems is built. These systems have a smaller footprint, and use cross–flow modulated non–dispersive infrared (NDIR) detection with a magnet–pneumatic detection method that is inherently drift–free. The ENDA–5000 series are superior continuous analysis systems that are perfect in the difficult field of exhaust gas measurement, where measurement errors cannot be tolerated. The series features a new intuitive touch panel that makes every operation available with the touch of a single button. The ENDA–5000 series systems are also designed for faster, more efficient maintenance. They are ideal for a variety of uses, including monitoring steam boiler, refuse incinerator, and electric power generation plant emissions to assure pollution standards are being met.
