Bacharach PCA3 Commercial/light industrial combustion analyzer
Product Support

The PCA®3 is the perfect tool for busy technicians and boiler contractors who need to ensure safe operating conditions, determine combustion efficiency and perform emissions testing. Up to 4 sensors can be installed, measuring all gases simultaneously, including NOx (calculated from NO or measured from NO + NO2). Sensors can be added in the field without down time or replaced using B-Smart® pre-calibrated sensors. The PCA®3 calculates values like efficiency, CO2 and CO air-free to help monitor combustion processes effectively and accurately.

The PCA®3 is designed for on-demand or semi-continuous sampling of light industrial, institutional, commercial and residential furnaces, boilers and appliances. It complies with regulations such as U.S. EPA test methods, EN 50379, CTM-030 and state/local protocols including SCAQMD. With sturdy metal gas and draft connectors, rugged construction, simple operation and quick, cost-effective maintenance, the PCA®3 is the workhorse of the industry.
