Page 13: Introduction
The Model 410i Analyzer measures CO concentration using advanced NDIR technology. The Model 410i combines proven detection technology, easy to use menu-driven software, and advanced diagnostics to offer unsurpassed flexibility and reliability. The Model 410i has the following features: • 320 x 240 graphics display •...
Page 14: Principle Of Operation
The Model 410i operates on the principle that carbon dioxide (CO absorbs infrared radiation at a wavelength of 4.26 microns. The sample is drawn into the Model 410i through the sample bulkhead, as shown in Figure 1-1. The sample flows through the optical bench.
