    Model T300 Gas Filter Correlation CO Analyzer

    The Model T300 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.

    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 14 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 extreme sensitivity.

    Model T300M Mid-Range Gas Filter Correlation CO Analyzer

    The Model T300M CO analyzer measures low ranges 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.

    Model T300U Ultra-Sensitive Gas Filter Correlation CO Analyzer

    The Model T300U Ultra-Sensitive CO analyzer has been developed specifically to address the challenges of low level monitoring as required, for example, in the US NCore network.  Using IR absorption with a Gas Filter Correlation Wheel, the T300U is designed to allow ultra-sensitive CO measurements while still meeting the requirements for use as a US EPA compliance analyzer.

    The optical bench is enclosed in a temperature controlled oven, dramatically decreasing instrument noise and drift.  The objective and field mirrors in the sample cell are gold plated to maximize signal to noise performance, while a temperature-controlled Nafion dryer on the inlet minimizes water interference caused by ambient humidity changes.  Periodically, the T300U seamlessly corrects its baseline by routing the sample through a heated catalytic CO scrubber.  This Auto Reference function corrects zero drift and reduces the effect of interferences.

    Model T360 Gas Filter Correlation CO2 Analyzer

    The Model T360 CO2 analyzer measures Carbon Dioxide 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 CO2 filled chamber and a chamber with no CO2 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 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 over a wide concentration range.
