Principle
The test chamber uses the French Taikang Compressor and environmentally friendly refrigerant to achieve low temperature control through the refrigeration system, the heating and humidification system uses the nickel-chromium alloy heating wire for rapid heating and humidification, and the control system uses the P.I.D + S.S.R coordinated control and thermal equilibrate temperature control method to accurately simulate the high temperature, low temperature, heat and humidity alternating environment to inspect the performance of the material.
Applications
Electronic Instruments, New Materials, Electrical, Vehicles, Metals, Electronics, Aerospace Materials
Standards
GB2423.1-2008/IEC6008-2-1-2007、GB/T 2423.2-2008、GJB150.3A－2009、GJB150.4A－2009、GB2423.22-2008、GBT 2424.5-2006、GB/T 10589-2008、GB/T2423.3-2008(IEC68-2-3)
Steps
1. Move the machine through the bottom PU activity wheel to the designated position and fix it.
2. Connect the power supply and ensure that the voltage is 380V.
3. Use the controller to set, you can choose the program mode or the setting mode to set the temperature and humidity parameters.
4. Place the sample on a sample rack with adjustable spacing to ensure uniform load-bearing distribution.
5. Start the equipment, monitor the test process, and display observations through the observation window and controller.
6. After the test, export the data Linear dispersion through USB interface or printer.
Notice
• Power supply voltage is 380V to avoid under- or reverse-phase.
• Sample load-bearing should be evenly distributed, not exceeding 20kg.
• Regularly check the automatic replenishment device of the humidification system.
• Pay attention to protection system alarms such as overtemperature and overload during equipment operation.
• Make sure the sealing plug is properly installed when using the test hole.
• Avoid running in extreme temperature and humidity conditions for a long time to prevent the equipment from aging.
• The equipment will automatically shut down after the fault alarm, and it needs to be checked and troubleshooted before starting.
