The 330 combustion analyzer can be used for commercial burner-boiler service. Among the items it automatically measures are temperature, carbon dioxide, carbon monoxide, efficiency, excess air, and draft. The results of these measurements are shown on a backlit four-line display. Features include modular probes, 30-second warm-up, smart sensors, 200 memory locations, USB interface, and a field-installable NOx upgrade. Complete diagnostic information on all sensors and systems always is available by pressing the i-button, the company says.
