Based on CV FAS Technology, VASTHI has developed Mercury Stack Gas Analyzer to detect the real time concentration of emission mercury and its cumulate emission rate. It consists of sampling probe, heat sampling pipe, pre-treatment system, stack mercury analyser, elemental mercury generator, ionic mercury generator and nitrogen.

Mercury stack gas analyzer is cold vapour atomic fluorescence spectrophotometer Technology. It is Fast response time, Low detection time limit and low temperature drift. Mercury stack gas analyzer is strong resistance to absorbability and real time Monitoring the dilution ratio, restore the concentration of HG and reflecting true working condition. Mercury stack gas analyzer is used for low velocity measurement technology to resolve the velocity limit of regular product.
