Online total lead analyzer, TPbG-3055


#Online total lead analyzer, TPbG-3055


The online automatic total lead analyzer is an optical method heavy metal online analyzer designed according to national environmental protection standards. It is applied to the simultaneous online analysis of various heavy metal elements in surface water, industrial process water and industrial wastewater. The measured heavy metal elements include environmental protection. The first and second categories of heavy metal prevention and control projects in the 12th Five-Year Plan for Comprehensive Prevention and Control of Heavy Metal Pollution.

Working principle:
After the water sample is mixed with the regulator, the lead in the sample reacts with the indicator to form a colored complex in the presence of an alkaline environment and an indicator (TPPS4), and the analyzer detects the change in the color and This change is converted into a lead value output. The amount of colored complex formed is equivalent to the amount of lead.
