  • Description

    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.

    *Note: The PCA®3 calculates CO2 value based upon other measured values during the combustion process. It does not measure CO2 directly.
