HASI-4000 Online Silica Analyzer

HASI-4000 Online Silica Analyzer

Online Silica Analyzer, HASI-4000, is a measuring equipment designed to enable measurement of low concentration range silica by using absorption spectrophotometry (molybdic acid blue method). HASI-4000 continuously measures the silica concentration in boiler water or ultrapure water for cleaning semiconductor by using Heteropoly blue method, and it can be also usefully applied for efficiency of driving turbine in power plant or QC in semiconductor · chemical industry.
