The PCA®2 is a commercial grade, handheld combustion and emissions analyzer for sampling of light industrial, institutional, commercial and residential furnaces, boilers and appliances. The PCA®2 is the perfect tool for service technicians and boiler contractors who need to ensure safe operating conditions, determine combustion efficiency, or perform emissions testing in combustion applications.
The PCA®2 directly measures and displays flue gas Oxygen (O2), Carbon Monoxide (CO), Stack Temperature, Draft, Differential Pressure, Combustion Air Temperature and optionally measures and displays Nitric Oxide (NO), Nitrogen Dioxide (NO2) and Sulfur Dioxide (SO2). Simultaneously, the PCA®2 calculates and displays combustion efficiency (EFF), Excess Air (EA), Carbon Dioxide (CO2), NOx and Oxygen reference values. The PCA®2 performs combustion calculations for ten fuels including, Natural Gas, Oil #2, Oil #4, Oil #6, Propane, Coal, Wood, Kerosene, Bagasse and Digester Gas. The large backlit graphic displays shows eight different measurements and calculated values simultaneously, and also has zoom capabilities.
