Horiba PG350 Analyzer


The device is capable of measuring up to 5 components (NOx/ SO2/CO/ CO2/O2). It uses the principle of absorption of infrared radiation (carbon monoxide, carbon dioxide, sulfur dioxide) –  chemiluminescence for nitrogen oxides and paramagnetic susceptibility (oxygen) for continuous measurements of emissions. The Horiba PG350 has an easy-to-read touch-screen display, equipped with an intuitive internal data logger, capable of storing the acquired values for long periods. The system allows data to be stored in CSV format, and is equipped with a removable memory. The analyzer is equipped with a self-diagnostic system. New compensations for the disruptions that arise due to the N2O and to the CO2, help to reduce the background noise in CO measurement.
