HORIBA - PG-250 - Portable Multi-Gas Analyzer

The PG-250 uses non-dispersive IR detection for CO, SO2, and CO2; chemiluminescence (cross-flow modulation) for NOx; and a galvanic cell or an optional zirconium oxide sensor for O2 measurements.

The instrument can interface directly with a laptop computer through an RS-232C interface to record measured values. Major features include a built-in sample conditioning system with sample pump, fliters, and a thermoelectric cooler. An optional auxiliary thermoelectric pre-cooler (PS-200) is available to condition samples which contain excess water vapor.

The performance of the PG-250 has been tested and verified under the U.S. EPA ETV program.

• The PG-250 is comparable to large-scale, specialized units in terms of accuracy and offers a high degree of selectivity in analysis. The NOX analysis unit uses a cross-modulation ordinary pressure chemiluminescence method, the SO2, CO, and CO2 unit uses a Non-Dispersive Infrared (NDIR) absorption method, and the O2 unit uses a Zirconia method using galvanized cell.
• The PG-250 can be hand-carried and attached to a notebook computer or optional preprocessing unit, allowing high-performance use no matter the location.
• The sampling unit has a filter, mist catcher, pump, electronic cooling unit, and NOX to NO converter built in.
• The PG-250 offers a large-scale, easy-to-read display.
