Three comprehensive test chambers mainly provide temperature and humidity environment for scientific research and production units such as aerospace, aviation, petroleum, chemical industry, electronics, communications, etc. At the same time, electrical vibration stress can be applied to the test products in the test chamber at a prescribed period for users To conduct a comprehensive stress screening test of temperature, humidity, and vibration on the whole machine (or parts), electrical appliances, instruments, materials, etc., in order to assess the suitability of the test article or evaluate the behavior of the test article. Compared with the effect of a single factor, it can more truly reflect the adaptability of electrical and electronic products to the changes of temperature, humidity and vibration in the environment of transportation and actual use, and expose the defects of products. It is a new product development, prototype test, product qualification certification An important test method essential for the whole process of the test. The controller of the three comprehensive test chamber adopts Japanese UNIQUE (optional Japanese OYO or American HONEYWELL controller) touch type true color LCD microcomputer controller, which is beautiful and beautiful. Three integrated test chamber adopts resistive high-precision touch screen operation mode, and can directly use USB mouse or touch pen to click on the screen for function selection or parameter setting. The programmable function has a capacity of 160Patten × 1600 step × 999 cycle. Screen display function: LCD display screen can display test conditions (including temperature section, cycle number, running time and remaining time, etc.). With program control and fixed value control functions, it is convenient to use various production conditions. The setting of temperature slope can freely control the running time and heating rate. Appointment start function, after the system time reaches the set time, the system will automatically run, you can freely control the running time and working conditions of the aging room. Power off restart function, you can choose cold start / hot start / interrupt operation. Temperature control adopts PID + SSR system synchronous coordinated control, which can improve the stability and life of control components and interface.
