Mid-Range Gas Filter Correlation CO2 Analyzer
Model N360M
-
Teledyne Advanced Pollution Instrumentation
The Model N360M measures carbon dioxide (CO2) by comparing infrared energy absorbed by a sample to that absorbed by a reference according to the Beer-Lambert law.The N360M uses Gas Filter Correlation (GFC) to overcome the interfering effects of various other gases (such as water vapor) that also absorb IR. The analyzer passes the IR beam through a spinning wheel made up of two separate chambers: one containing a high concentration of CO2 known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO2 in the sample chamber is computed by taking the ratio of the instantaneous measure and reference values and then compensating the ratio for sample temperature and pressure. A nitrogen purge system is provided for the GFC wheel assembly to eliminate the effects of ambient CO2, if necessary.

Mid-Range Gas Filter Correlation Carbon Monoxide Analyzer
Model T300M
-
The Model T300M CO analyzer measures low to mid 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. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed 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 2.56 meters.The energy loss through the sample cell is compared with the span reference signal provided by the filter wheel 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 high signal to noise ratio, allowing excellent performance from low to high range.All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.The Model T300M comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.
