Overview
KESIONOTS KS-HD150LD low/high temperature test chamber is an environmental test equipment for high and low temperature Reliability test of industrial products. It is suitable for inspection of electronic and electrical, automobile and motorcycle, aerospace, ship weapons, universities and R & D institutions and other related products. The performance indicators of parts and materials under high temperature and low temperature (alternating) cycle conditions are widely used in product design, improvement, identification and aging tests.
Features
1. Temperature range is wide, up to -20 ℃ to 150 ℃.
2. Temperature control accuracy is high, the control accuracy is +/- 1 ℃, Fluctuation is +/- 0.5 ℃.
3. Using high-quality materials, the outer box is high-grade cold-rolled sheet paint, and the inner box is stainless steel.
4. Equipped with a variety of protection devices, such as no fuse switch, Compressor overload protection, refrigerant high voltage protection, over temperature protection, etc.
5. The controller can be selected from the Korean "TEMI" or Japanese "OYO" brand.
6. The Compressor can be selected from "Taikang" or German BITZER brand.
7. Provide standard test holes, viewing windows, box lights and other accessories.
Principle
The test chamber creates and precisely controls the required high or low temperature environment in a closed chamber through a refrigeration system (e.g. Air-Cooled/single-stage Compressor or wind, Water-Cooled/double-stage Compressor) and a heating system. The controller system adjusts the cooling and Heating power according to the set parameters, so that the temperature in the working room changes according to the preset program to simulate the extreme temperature conditions that the product may encounter in actual use.
Applications
Electronics and electricians, automobiles and motorcycles, aerospace, ships and weapons, colleges and universities, R & D institutions
Standards
GB2423.1、GB2423.2、GJB150.3、GJB150.4、IEC、MIL
Steps
1. Place the device in a smoothly ventilated place and connect it to the required power supply (220VAC +/- 10% 50/60Hz or 380VAC +/- 10% 50/60Hz).
2. Turn on the power switch and start the device.
3. Set the required temperature program through the controller (e.g. TEMI or OYO), including target temperature, lifting rate, holding time, etc.
4. Place the sample to be tested on the Shelf in the studio and close the box door.
5. Start the test program and the device starts running.
6. During the test, the sample status can be observed through the viewing window.
7. After the test, the device stops running according to the program, and the sample is taken out after the temperature in the box approaches the Ambient Temperature.
8. Power off the device.
Notice
* The equipment should be installed in a well-ventilated environment without direct sunlight, away from heat sources and flammable and explosive materials.
* Power supply voltage is consistent with equipment requirements and grounded reliably.
When placing the sample, the air duct should not be blocked to ensure smooth air circulation in the box.
* During operation, do not open the door frequently, so as not to affect the Temperature Stability and equipment life.
The cooling rate of the equipment is about 1.0 ° C/min. If a faster rate is required (a decrease of 5 to 10 ° C per minute), it is a special condition and needs to be confirmed in advance.
* Regularly check the chilling down system (if it is Water-Cooled type, ensure that the chilling down water supply is normal) and the effectiveness of various protection devices.
After the low temperature test, if you need to open the box door, you should pay attention to the possible damage caused by frost and temperature difference.
When the equipment malfunctions, the fault warning system will prompt, and professionals should be contacted in time to deal with it. Do not disassemble it yourself.
