Product Description
Nanjing Annai Testing Equipment Co., Ltd. With the rapid development of modern industrial technology, the application fields of electrical and electronic products are becoming increasingly broad, and the environmental conditions they experience are becoming more and more complex and diverse. Only by reasonably specifying the environmental conditions of the product and correctly selecting the environmental protection measures for the product can the product be protected from damage during storage and transportation and be safe and reliable during use. Therefore, artificial simulated environment testing of electrical and electronic products is an indispensable and important link to ensure their high quality. Artificial simulated environmental tests are scientific summaries of actual environmental impacts and have the characteristics of typification, standardization, ease of use, and ease of comparison. The diversification of environmental conditions and the importance of environmental testing also put forward more stringent requirements for environmental testing equipment.
The high and low temperature shock test chamber can be used to assess and determine the adaptability of electrical and electronic products or materials for storage and use under harsh environmental conditions with sudden temperature changes.

Control system
The system adopts programmable program control and has sufficient program capacity (you can compile, modify and store programs by yourself. Each program can set segments; cycle times). The controller is equipped with a . inch touch screen and our company's own The main control system core processing component (microprocessor) of the developed software system adopts Siemens system, which can set and display the heating and cooling rate, heating and cooling time, constant temperature running time, segmented running time, total running time, test curve, and Displays set parameters, measured parameters, fault records, historical records and help information, heater and refrigeration system working status, and has automatic operation of test procedures. The control program is compiled using human-machine dialogue and only needs to set the temperature, humidity and time to realize the automatic operation function. The detection device can automatically carry out detailed fault display and alarm; it adopts .3-inch color LCD touch screen with Chinese character menu prompts; human-machine dialogue interface: color comes with B-lithium battery for data backup. Temperature setting accuracy: .℃; Time setting accuracy: .
Fault information: When a system failure occurs, the control system records and displays the possible causes of the failure status and recommended solutions in Chinese. Equipped with a universal computer communication interface, it is equipped with a complete machine time accumulation timer.
