Function and design

3.1

Layout

The analyzer is a compact table-top device with permanently installed main compo-
nents. Further accessories and reagents are required for the measurement process.

Control of the analyzer and analysis of the measurement data is performed via the mul-
tiWin software.

All components of the analyzer operated or serviced by the user can be accessed via the
two doors on the front, the left-hand removable side wall or the top cover.

The analyzer consists of the following main components:

¡

Sample supply system

¡

Gas box and hose system

¡

Combustion system

¡

Measuring gas drying and cleaning

¡

Detector

¡

Indicator and control elements, connections

¡

Electronics

¡

Accessories
