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