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.
