Model T320U - Ultra-Sensitive Gas Filter Correlation N2O Analyzer

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 using the included APIcom™ software.
