Overview
GDJS-500B high and low temperature alternating damping heat test chamber is produced by ZKHS, suitable for aerospace products, information electronic Instruments, materials, electrical, electronic products and various electronic components in high and low temperature or heat and humidity environment inspection of its performance indicators. The equipment adopts advanced control system and refrigeration technology to ensure accurate and stable test environment.
Features
1. The box is processed by numerical control machine tool, which is beautiful and easy to operate
2. The liner is imported stainless steel mirror plate, and the shell is sprayed with A3 steel plate, which has high cleanliness
3. The replenishment tank has automatic protection for water shortage, which is convenient for water source replenishment
4. Large observation window with lighting, clear observation of the situation in the box
5. The humidification system piping is separated from the control circuit board to improve safety
6. Waterways and circuit systems are door-opened for easy maintenance and repair
7. The box body insulation adopts ultra-fine fiberglass insulation cotton to reduce energy loss
8. The left side of the box is equipped with a test hole for external test lines
9. The temperature and humidity control instrument has a 7.0-inch large screen and supports Chinese and English interfaces
10. With 100 sets of programs and 1000 segments of 999 cycle steps capacity
11. The controller has a screen lock function to prevent accidental touch and shutdown
12. Supports RS-232 or RS-485 communication, and can design programs on the computer
13. With automatic calculation function, accurately correct temperature and humidity changes
14. The refrigerator adopts the original French "Taikang" fully enclosed Compressor
15. Multi-wing blower is used for strong air circulation, with uniform temperature and humidity distribution
16. The air circuit circulation design makes the temperature and humidity stabilize quickly, reducing the test cost
Principle
The test chamber precisely sets the temperature and humidity parameters through a programmable controller. The refrigeration system adopts a unit or binary low temperature circuit design, and cooperates with a multi-wing blower to achieve strong circulation to ensure uniform temperature and humidity in the test area. The heating, humidification and dehumidification systems work independently, and the environmental conditions are corrected in real time through automatic calculation function to achieve stable control.
Applications
Aerospace Products, Information Electronic Instruments, Materials, Electrical, Electronic Products, Various Electronic Components
Standards
GB/T10592－2008、GB/T10586－2006、GB/T2423.1－2008、GB/T2423.2－2008、GB/T2423.3－2006、GB/T2423.4－2008、GJB150.3A-2009、GJB150.4A-2009
Steps
1. Turn on the power supply and check whether the voltage meets the requirements of AC220V +/- 10% or AC380V +/- 10%
2. Open the control panel, select the Chinese and English interface, and set the temperature and humidity program
3. Put the test sample into the studio to ensure stable placement
4. Connect the external test line to the test hole on the left side of the box (if necessary)
5. Start the device, the monitoring screen shows real-time operation Linear dispersion
6. After the test is completed, stop the equipment according to the program and take out the sample
Notice
• Operating Environment Temperature should be maintained at 5 ℃~ 30 ℃, humidity ≤ 85% R.H
• Regularly check the water level of the replenishment tank to avoid protection shutdown due to water shortage
• Make sure the power is disconnected during maintenance to avoid the risk of electric shock
• Do not open the door frequently when the equipment is running, so as not to affect the temperature and humidity stability
• Use a soft cloth when cleaning the box to avoid scratching the stainless steel surface
• In case of over-temperature, water shortage and other alarms, check and troubleshoot immediately
• If not used for a long time, the power supply should be cut off and the equipment should be kept drying
