Description

The EX3000-301 Ammonia Gas Analyzer is an ammonia gas (NH3) monitoring system specifically designed for monitoring of stack emissions, motor exhausts, ambient air, and gases.

The analyzer is mounted on a 19" rack. The front panel incorporates a flow meter to check the circulation of the analysed gas or zero gas as well as a large LCD display touch screen.

This tactile screen displays the analyzer results and provides menus and messages, allowing the user easy control over the operation of the analyzer.

The measurement principle is based on the absorption spectrum of ammonia gas (NH3) in the UV range.

The periodic structure of the absorption bands coming from the different levels of rotational energy of the gas molecules is analysed by performing a Fourier Transform on the absorption spectrum with a high speed DSP (Digital Signal Processor).

As opposed to the FTIR approach - where the Fourier Transform needs moving optical components - the Fourier Transform in the UV range is done by solid state optics and electronic circuits, which constitutes a more economical solution.

The selectivity of the analyzer is guaranteed by the typical periodic structure of the analysed gas, unique for each gas.
