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.
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
The Model T300 comes with NumaView™ Software.
