A 450 flue gas analyser, Wöhler

Description

The A 450 flue gas analyser from Wöhler is a universal instrument that contains all the measurement and control functions required for analysis.

Its small dimensions and low weight make it optimal for easy carrying. The housing is robust and compact.

 

Benefits

Easy to manage

It is easy to use and comparable to handling a smartphone.

The (touch) display shows all measurement data.

The choice of features is similar to that on smart mobile devices.

The menu is made up of icons, and individual items can be opened simply by tapping.

Special adaptation

Easy adjustment to set the burner.

Monitor

The analyser monitor has a high resolution display.

Sensors

The analyser’s sensors are protected against condensation by a three-stage filter that prevents moisture ingress.

A smoke duct is provided through each sensor module (oxygen, carbon dioxide, nitrogen monoxide).

Accurate, reliable and stable measurements

The measurements are displayed at as numerical values or as a graph in Wöhler A 450.

The app can be used to read measurements that have already been taken and to take new ones.

Measuring at points with poor accessibility is easy.

Measurement data can be stored v various formats (also suitable for electronic transmission).

Connection and display is also possible on other smart devices viawireless LAN ( smartphones, Android and iOS tablets ).

Different types of A 450

The flue gas analyser is available in different models depending on the application and the field of use.

See the attached documentation for more details.
