Bacharach ECA 450 Combustion Efficiency Analyzer

The ECA 450 is an industrial-grade analyzer ideal for professionals concerned about combustion efficiency, environmental compliance, or both. Accommodating up to seven sensors, simultaneous measurements, and calculated parameters are evaluated to ensure that industrial equipment is meeting environmental regulations while burning safely and efficiently.

The ECA 450 is designed for on-demand or semi-continuous sampling of industrial furnaces, boilers, and other industrial combustion equipment. It complies with regulations such as U.S. EPA test methods, EN 50379, CTM-030, and state/local protocols including SCAQMD.

Note: The ECA 450 calculates CO2 value based on other measured values during the combustion process. It does not measure CO2 directly.

FEATURES Measures up to 7 gases simultaneously (minimum O2 and CO), including NOx, SOx and combustibles Sensors are easily replaced or upgraded in the field Rugged suitcase design with a large, easy-to-read display Built-in printer for instant traceability and record-keeping
