Model WDG-HPII Analyzer

Model WDG HP Analyzer

Overview
The WDG-HPII Series offers a unique chimney-effect/convective sampling technology that incorporates the advantages of insitu probe high particulate sampling with high temperature and corrosion resistance of extractive analyzers. The HPII is ideal for combustibles and oxygen measurement on applications in cement and lime kilns, foundry and metals production furnaces, coal, wood waste and heavy oil-fired boilers, black liquor recovery boilers. Available with Series 2000 controller.
