Model 300E
Gas Filter Correlation CO Analyzer
The Model 300E measures low ranges of carbon monoxide by comparing
infrared energy absorbed by a sample to that absorbed by a reference
gas according to the Beer-Lambert law. This is accomplished with a Gas
Filter wheel which alternately allows a high energy light source to
pass through a CO filled chamber and a chamber with no CO present. The
light path then travels through the sample cell, which has a folded
path of 14 meters.
The energy loss through the sample cell is compared with the span
reference signal provided by the gas filter to produce a signal
proportional to concentration, with little effect from interfering
gases within the sample. This design produces excellent zero and span
stability and a high signal to noise ratio allowing extreme
sensitivity. Multi-tasking software gives real time indication of
numerous operating parameters and provides automatic alarms if
diagnostic limits are exceeded.
Built-in data acquisition and internal memory allows logging multiple
parameters including average and instantaneous values, calibration data
and operating parameters. Stored data are easily retrieved through the
serial port or optional Ethernet port via our APIcom software or from
the front panel, allowing operators to perform predictive diagnostics
and enhanced data analysis by tracking parameter trends.
The Model 300E features rugged construction and is designed to perform
with a minimum of attention. In the event maintenance is required,
modular construction makes service a simple operation.
