New TAsG-3057 Online Total Arsenic Analyzer
New TAsG-3057
ONLINE TOTAL ARSENIC ANALYZER
The online and automatic total arsenic analyzer is an optical method heavy metal online analyzer designed in accordance with national environmental protection standards. It is applied to the simultaneous online analysis of various heavy metal elements in water quality such as surface water, industrial process water and industrial wastewater.
Measuring principle:
After the water sample is digested by acid at high temperature and then mixed with the regulator, the arsenic in the sample reacts with the indicator to form a colored complex in the presence of an acidic environment and an indicator, and the analyzer detects the change of the color. And convert this change into the total arsenic value output. The amount of colored complex formed is equivalent to the total amount of arsenic.
