Applications

Description

The Model T320U N₂O analyzer measures Nitrous Oxide 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 N₂O filled chamber and a chamber with no N₂O present. The light path then travels through the sample cell, which has a folded path of 14 meters. Inferences from H₂O and CO are eliminated using a Nafion dryer and precious metal catalyst.

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 interference free performance in the low 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 T320U is available with the Numaview™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.
