Overview
KESIONOTS KS-HD1000LC low/high temperature test chamber is an environmental test equipment suitable for high temperature and low temperature Reliability test of industrial products. The equipment is mainly used for inspection of electronic and electrical, automobile and motorcycle, aerospace, ship weapons, colleges and universities, R & D institutions and other related products under high temperature, low temperature (alternating) cycle changes of various performance indicators, serving product design, improvement, identification and inspection.
Features
1. Temperature range options available, up to -70 ° C to 150 ° C.
2. Temperature control accuracy, analytical accuracy of +/- 0.1 ℃, control accuracy +/- 1 ℃.
3. The inner box is made of stainless steel, and the outer box is made of high-grade cold-rolled sheet paint, which is sturdy and durable.
4. Equipped with a variety of protection devices, such as no fuse switch, Compressor overload protection, refrigerant high voltage protection, over-temperature protection, etc., to ensure safe operation.
5. Optional well-known brand controllers (such as Korean "TEMI" or Japanese "OYO") and Compressors (such as "Taikang" or German Bitzer).
6. Standard configuration includes practical accessories such as viewing window, test hole, box light, Shelf, etc.
Principle
The low/high temperature test chamber simulates and precisely controls the required extreme temperature environment in a closed box through a refrigeration system and a heating system. The refrigeration system uses Air-Cooled or wind and Water-Cooled Compressors for cooling according to the set low temperature requirements; the heating system achieves rapid heating through electric heating elements. High Accuracy temperature sensors and controllers monitor and adjust the temperature in the box in real time to cycle between high and low temperatures according to a preset program to test the Reliability of the sample under temperature stress.
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 sample to be tested correctly on the Shelf in the test chamber.
2. Close the door and make sure the sealing is good.
3. Turn on the power supply and choose a 220V or 380V power supply according to the equipment requirements.
4. Set the required Temperature range, rate of change and cycle program parameters on the controller.
5. Start the equipment, and the refrigeration and heating system starts to work, so that the temperature in the box runs according to the set program.
6. During the test, the sample status can be observed through the viewing window.
7. After the test is completed, the equipment stops running according to the program. After the temperature in the box returns to a safe range, the sample can be taken out by opening the door.
Notice
• Equipment should be installed in a well-ventilated, non-direct sunlight, away from heat sources and flammable and explosive materials.
• Before power on, please confirm that the Power supply voltage matches the equipment requirements (220VAC +/- 10% or 380VAC +/- 10%).
When placing samples, the total volume should not exceed 2/3 of the volume of the studio, and the air duct should not be blocked.
• During the operation of the equipment, do not open the box door frequently to avoid affecting the temperature stability and equipment life.
• Regularly check the refrigerant pressure, electrical connections and protective devices to ensure their normal operation.
• After the low temperature test, if the high temperature test is required, it is recommended to warm the box to close to room temperature to avoid sudden heating to produce condensate.
• When the equipment fails, you should refer to the instructions for investigation or contact a professional for maintenance, and do not disassemble it yourself.
• Pay attention to the cooling rate marked on the equipment (about 1.0 ° C/min), and the special requirements for rapid cooling (5-10 ° C drop per minute) are optional conditions.
