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 NO_x (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.

• Full color, multilingual graphic display with backlighting, zoom display and dimming mode
• Sturdy metal gas and draft connectors
• Measures up to 4 gases simultaneously
• Exclusive B-Smart® field-replaceable sensors reduces downtime and calibration costs
• Ten different fuels – ability to load custom fuels
• Automatic CO over-range protection
• Measures and displays flue gas oxygen, carbon monoxide, stack temperature, combustion air temperature, draft and differential pressure
• Loss and efficiency are calculated from standard heat-loss calculations or using the Siegert formula for Europe
• NOx reading from NO+NO2 or calculated from NO only
