In-situ analyzer

The Procal 200LR In-Situ IR analyzer measures up to six gases simultaneously, including CO, CO2, SO2, NOx, H2O and NH3, using the Procals gas filter correlation technique. This, combined with powerful correlation capabilities, eliminates cross-sensitivity problems. In-situ installation provides a high-speed response for low-NOx burner controls. Probes can be installed into the ducts from each boiler. Added benefits include low-cost installation and maintenance compared to extractive systems. Repeatability and accuracy is ۬ percent, and units are designed for in-situ flue gas temperatures of up to 650 F. Close-coupled models allow operating temperatures up to 2,550 F respectively.
