Overview
HZAOC GDJS-225D High and Low Temperature Alternating Damping heat testing chamber is suitable for investigating the moisture resistance of electrical and electronic products, components, parts and materials under different temperature and humidity conditions, and can also be used for storage, transportation and use in high and low temperature environments.
Features
1. The box adopts the overall structure, the inner side is stainless steel plate, the outer side is sprayed steel plate, and the thermal insulation performance is good.
2. The door is sealed with double-decked silicone rubber, and the observation window is a multi-layer conductive film tempered hollow Glass with frost-proof heating wire and lighting.
3. Adopt French "Taikang" fully enclosed Compressor, use environmentally friendly refrigerant, and the refrigeration system is safe and reliable.
4. The heater has low thermal inertness and long service life. The humidification adopts the steam boiler electric heating method and is equipped with a dry burning prevention device.
5. The control system adopts High Accuracy Digital Temperature and Humidity Controller, equipped with multiple safety protection and independent over-temperature protector.
6. The electrical system is equipped with an interlock device to ensure that the heating and humidification system does not work when the fan is not started.
Principle
The test chamber realizes low temperature environment through refrigeration system, high temperature environment through electric heating system, and humidifies by steam boiler electric heating to realize heating and humidity environment. The control system coordinates the work of refrigeration, heating, humidification and circulating fans according to the set temperature and humidity program, so that the air in the box circulates according to the upper air supply and lower air return mode, so as to simulate the required temperature and humidity conditions inside the studio.
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
Steps
Connect 380V +/- 10% power supply.
2. Set the required temperature, humidity and time program through the operation panel.
3. Place the sample in the studio and close the sealing door.
4. Start the equipment, the circulating fan starts to work, and the refrigeration, heating, and humidification systems operate according to the program.
5. During the test, the specimen can be observed through the observation window and lighting.
6. After the test reaches the set time or condition, it will automatically stop and the sample will be taken out.
Notice
Equipment needs to be grounded reliably and ensure that the power supply meets the requirements.
• The sample placement should not block the air supply and return trend.
• Check the water level before operation to prevent the humidifier from dry burning.
• Do not open the box door frequently when the equipment is running.
• When the fault indicator light is on, the fault should be eliminated before operation.
• Regular maintenance to ensure that sealing strips, Filters and other components are in good condition.
