Profesional manufacturer & supplier for test equipment & analytical instruments since 2003.
Environmental Sulfur Dioxide Testing Chamber
Standards: DIN 50018, GB/9789-88
Features & Principle
l Enclosure material: PVC reinforced hardened plastic sheet, smooth and aging resistant, corrosion resistant
l Liner material: PVC plastic board
l Cabinet cover material: high quality imported PVC shock resistance board, easy for observation when testing, water for sealing to avoid out gas escape
l Gas waste discharge system located on the right side of the control cabinet
l PP high temperature resistant board for heating, water trough heating mode, fast temperature rise and uniform temperature
l Equipped with 1pc sulfur dioxide gas slack barrel
l U type Ti alloy high speed electric heating heating tube
l Intelligent high accuracy digital PID MCU
l Gas enter the chamber and mix with the water vapor then generate sulphurous acid corrosion resistant pipe as the gas guide tube
l Over temperature & water lacking
l Fuse free protection switch
l Test running indication
l The waste gas is filtered by activated carbon and sodium carbonate then exhaust to outside
