Configuration of Salt Fog and So2 Corrosion Chamber

① Workroom	Made of corrosion-resistant materials such as glass fiber reinforced plastics. Standard configuration features a round rod and V-shaped groove design. Test pieces can be placed freely and angles can be adjusted as needed. Customized insert sample holders are also available upon request.
② Spray tower	Tower sprayer, it guides the spray evenly throughout the workroom through the spray tower. The spray nozzle is a non-crystalline glass nozzle.
③ Refrigerating system	The use of mechanical compression refrigeration, such as fully closed French TECUMSEH compressor using environmentally friendly refrigerant.
④ Air circulation system	The centrifugal fan is used to make the temperature, humidity, corrosion gas and other test parameters inside the workroom more uniform through the design of up-air and down-air circulation.
⑤ Heating system	The alloy electric heat pipe is used as the heating element, and the heating temperature can be accurately controlled by the programmable controller.
⑥ Humidity system	External isolation, stainless steel surface evaporation humidifier, which can adjust the humidity of the workroom according to the test requirements.
⑦ Control system	Programmable color LCD touch screen controller with Ethernet connectivity for remote monitoring and operation.
⑧ Saturated barrel	Used to preheat and humidify the air entering the workroom, so that the air reaches a saturated state, so as to ensure the stability and consistency of the test environment.
⑨ Salt solution tank	It is used to store the prepared salt solution. It is connected to the spray tower through the pipe to provide the salt solution for the spray.
⑩ NAOH tank	SO2 Exhaust Device Drain SO2 into the NAOH tank.A spray device is installed in the tank to better dilute sulfur dioxide.Make the workplace clean and safe.
⑪ SO₂ gas cylinder	Store SO₂ gas to provide the corrosion gas needed for testing, and precisely control the flow and timing of SO₂ gas entering the workroom.
⑫Air source(option）	To provide compressed air for the spray tower, so that the salt solution can be atomized into salt spray.
