Overview
HZAOC GDJS-010B high and low temperature alternating damping heat test chamber is suitable for investigating the moisture resistance of electrical and electronic products, components, parts and materials under different temperature and humidity conditions, as well as the adaptability test of storage, transportation and use in high and low temperature environments.
Features
1. The box adopts the overall structure, the inner side is 1.0mm SUS304B stainless steel plate, the outer side is 1.0mm Cold rolled steel plate sprayed, and the thermal insulation material is ultra-fine Glass thermal insulation cotton.
2. The door sealing is made of double-decked silicone rubber sealing material, the observation window is a multi-layer conductive film tempered hollow Glass, and the built-in special heating wire is frost-proof and lighting.
3. The side of the box is equipped with φ 50mm test hole, and the stopper is silicone rubber low foam material, which has both high and low temperature resistance and thermal insulation efficiency.
4. The heater adopts a porcelain frame nickel-chrome wire electric heater, which has little thermal inertia, long service life, and stable and reliable control.
5. The humidification system adopts the steam boiler electric heating humidification method, and is equipped with water level control and dry burning prevention devices.
6. The control system adopts LCD Touchscreen temperature and humidity controller, equipped with multiple safety protection measures, including phase loss protection, over-temperature power-off protection, etc.
Principle
The test chamber adjusts the temperature and humidity in the working room through the evaporator, electric heater, humidifier, fan and other equipment in the air conditioning cabinet. The temperature transducer is placed in a trend, and the control system precisely controls the heating and humidification process through PID signals and solid state relays to ensure stable temperature and humidity.
Applications
Electrical and electronic products, components, parts and materials moisture resistance test, high and low temperature environment storage adaptability test, transportation adaptability test, use adaptability test
Standards
GB/T2423.3-2001、GB/T5170.5-96、GB/T10586-89
Steps
1. Turn on the power supply and check the power supply and function buttons of the control system panel.
2. Set the required temperature and humidity parameters and adjust them through the LCD Touchscreen controller.
3. Start the circulating fan to ensure that the heating and humidification systems start normally.
4. Put the sample in the studio, close the door and make sure the sealing is good.
5. Monitor the test process and observe changes in temperature and humidity until the test is completed.
Notice
• Check whether the Power frequency is AC380V before operation to avoid voltage mismatch.
• Make sure the circulating fan starts normally, otherwise the heating and humidification system will not work.
• Regularly check the over-temperature protector and safety protection device to prevent equipment failure.
• When using the test hole, pay attention to the sealing of the stopper to maintain the thermal insulation efficiency.
• To avoid dry burning of the heater, the humidification system needs to keep the water level normal.
