1 Introduction
1.1 PCA 2 General Description
The PCA 2 is a commercial-grade hand-held combustion and emissions
analyzer designed for on-demand sampling of light industrial, institu-
tional, commercial and residential furnaces, appliances, and boilers. The
basic instrument is supplied with a probe and hose assembly, instruction
manual, factory calibrated smart sensors, 4 'AA' alkaline batteries, Data
Download Software with USB cable and carrying case.
Because of the PCA 2’s ability to measure up to four gases simultaneously,
it is the perfect tool for service technicians, inspectors and boiler contrac-
tors who need to determine combustion efficiency, excess air, stack gas O
2
and CO levels, stack temperature, draft, and differential pressure. The
analyzer can also directly measure and display NO, NO
2
and SO
2
with the
installation of the appropriate sensors. Combustion efficiency calculations
can be conducted for the following fuels: natural gas, oil #2, oil #4, oil #6,
propane, coal, wood, kerosene, bagasse, and digester gas. A large backlit
graphical display shows up to eight combustion test values simultaneously,
and includes a zoom capability that provides an extra large display of just
the O
2
, CO, and combustion efficiency values.
Smart sensor technology allows a new sensor to be installed in the field
without having to calibrate the analyzer before use. New and innovative
probe and analyzer designs allow the PCA 2 to be easily serviced, thus
lowering the cost of ownership.
Advanced data storage and communication features allow the operator
to store up to 500 individual combustion test records, which can later be
recalled for viewing, printing, or downloading to a personal computer. In
its data logging mode, the analyzer can store an additional 500 data logged
records.
An optional AC power adapter allows the analyzer to run continuously for
data logging purposes.
The optional sample conditioning probe is recommended when measuring
NO
2
and SO
2
to ensure the highest degree of measurement accuracy.
