A 550 flue gas analyser, Wöhler

Description

The A 550 flue gas analyser, Wöhler is a universal portable device for flue gas analysis. Up to 5 sensors can be connected (depending on the measurement quantity), allowing a wide range of combinations and applications.

Benefits

Easy to use

Despite its ability to be implemented in challenging, harsh working conditions and environments, maintains an ease of use comparable to handling a smartphone.

Individual functions can be controlled from a smartphone via a 7-inchcolour touchscreen.

Getting measuring values is easy.

Monitor

The monitor is designed for very good visibility.

The large display, clear layout and graphical presentation of the readings make it easy to read.

Sensors

Accurate, reliable and stable measurements
