The unit is controlled by using two decade thumbwheel switches adjustable from 00 to 99, and a three position ozone level switch for low, medium and high settings. The NOxGen 3 R provides the option of remote control using TTL levels for all operational functions. The Signal Group’s NOxGen 3 comes in a 19” rack type, 3 units high enclosure. It can be bench top used or fitted into a 19” rack console. For bench top use there are extendible feet at the front which can be used to tilt the angle of the instrument back for ease.

Inside the Heated Sample Line: Why Temperature Integrity Matters in Gas Analysis
In the realm of precise gas analysis, particularly within continuous emissions monitoring systems (CEMS) and process control applications, the integrity of the sample from the point of extraction to the analyser is paramount. A critical, yet often underestimated, component in maintaining this integrity is the heated sample line. Failure to
