The PG-250 is a portable stack gas analyzer that can simultaneously measure up to five separate gas components using the same proven measurement methods used in HORIBA's line of permanent CEMS. The PG-250 is ideal for CEMS certification testing (RATAs) or for use when stack gas emissions must be monitored periodically at one or multiple stacks.
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.
