MFG Test Chamber

Name: MFG Test Chamber
Brand: Xi'an LIB Environmental Simulation Industry

In the MFG(Mixed Flowing Gases) test chamber, the mixing ratio, flow rate, temperature, humidity and other environmental parameters of various gases can be accurately controlled,testing the corrosion resistance of various materials, electronic components and other products in the environment of mixed corrosive gases.

LIB MFG test chamber can perform single gas test and can also perform mixed(H2S/NO2/CL2/SO2,etc ) gas test.

Model: GCM-100, GCM-225, GCM-500, GCM-800, GCM-1000

Standard: ASTM B827, ASTM B845, IEC 60068-2-60, IEC 60068-2-42, MIL-STD-810

Features and Benefits of MFG Test Chamber

1. A variety of different gases, such as H2S,NO2,CL2,SO2,NH3,etc. are precisely mixed in a set proportion. High precision gas flow controller with control accuracy of parts per billion (ppb).

2. In addition to gas control, the temperature range can be controlled from 15 ° C to 100 ° C, and the humidity can be adjusted from 30% to 98%RH, which is broad and accurate temperature and humidity regulation to meet different test needs.

3. Equipped with high-precision gas flow controller, temperature sensor, humidity sensor, which can accurately control various parameters in the MFG test chamber to ensure the stability and accuracy of the test conditions.

4. The concave and convex design, silicone seal, electromagnetic lock are used to ensure the tightness of the test chamber during the test, prevent harmful gases from leaking.

Configuration of MFG Test Chamber

①Workroom	The workroom’s SUS304 stainless steel material is covered with a layer of glass steel, which both prevents corrosion and enhances the robustness of the equipment.
②Air circulation system	Composed of a centrifugal fan and a drive motor, the air in the test chamber is continuously circulated to ensure the uniform distribution of environmental parameters such as temperature, humidity and gas concentration in the chamber.
③Heating system	High power resistance wire, quickly raise the temperature in the test chamber.
④Control system	PID accurately controls temperature, humidity, gas flow and other parameters, and also has monitoring, alarm and data recording functions.
⑤Cooling system	Composed of compressor, condenser, throttle mechanism and evaporator. The temperature in the chamber is reduced by absorbing heat through the evaporation of the refrigerant.
⑥Exhaust device	NAOH solution tank for diluting H2S/NO2/CL2/SO2, making the workplace clean and safe. Dilute H₂SO₄ tank can also be added to dilute alkaline gases.
⑦Humidity system	Steam humidification, quickly increase the humidity inside the chamber.
⑧Gas flowmeter	Accurately measure and control the gas flow into the test chamber to ensure that the concentration of the gas inside the chamber reaches the set value required by the test.
⑨Gas sensor	The high-precision gas sensor can monitor the concentration, type and other parameters of the gas in the chamber in real time, and feed the data back to the control system.
