Many Governments and local Authorities around the world require industries to monitor and report the levels of pollutants contained in emissions from industrial operations as well as recycling and incineration facilities. To abide by these regulations, Data Acquisition and Handling Systems (DAHS) are used to accumulate, analyse, and report on what can be extremely large volumes of data.
A Data Acquisition and Handling system (sometimes abbreviated to DAS or DAQ) is a system which
The DAHS then uses the digital data, analyses, and checks measured levels of substances recorded against limits for those substances and produces regular reports and sometimes warnings/alerts to the appropriate personnel or transmitted to additional systems.
