Product Description

H2S,SO2,NO2,CI2 Drive-in Gas Test Chamber Accelerated Drive-in Test Chamber


Gas corrosion system:

Working principle Equipment design two sets of boxes, external temperature and humidity air conditioning cabinet + sample room. The air conditioning system has refrigeration system,heating system, humidification system, mixed gas inlet, exhaust gas discharge filter and other devices.


Before diluting corrosive gases are mixed, the air conditioning system creates the test temperature and humidity in the chamber outside the sample room. When the temperature and humidity are constant, the gas is input at the same time. The gas concentration is measured by calculating the volume ratio formula, and then the mass flowmeter is used for effective control, so that it reaches the specified range.In the test chamber, the gas is mixed evenly through the fan.


In the sample room, the air in the sample room is discharged through pumping, so that low pressure is formed in the sample room. Compared with the space outside the sample room in the test chamber, the wet air in the sample outdoor area is pumped into the sample room through the pipe. By recording the data, the flow rate of the air extracted from the sample chamber can be adjusted to obtain the specified number of gas volume changes per hour.

Load Condition:
  • The total mass of the load placed per cubic meter of studio volume shall not exceed 80KG
  • The load physical volume is not greater than 2/5 of the studio volume
  • At any section perpendicular to the wind direction of the inner circulation, the total area of the sample load should not be greater than 1/3 of the cross-sectional area of the studio in this direction. Oversized sample load will affect the air balance and smooth of the chamber
