Applications
âThis product is suitable for testing equipment required in aviation, automobiles, home appliances, scientific research and other fields. It is used to test and determine the parameters of electrical, electronic and other products and materials after high temperature, low temperature, humidity and heat or constant temperature environment changes. and performance.
Box structure
âThe box body is processed and formed by CNC machine tools, with a beautiful and elegant shape, and a non-reaction handle, which is easy to operate.
âThe inner liner of the box is made of imported stainless steel (SUS304) mirror panel made by argon arc welding, and the outer shell of the box is made of A3 steel plate sprayed with plastic.
âUsing a (7.0-inch) ultra-large screen, the screen operation is simple and the program editing is easy.
âThe large observation window is equipped with lighting to keep the inside of the box bright, and double-layer glass is used to clearly observe the conditions inside the box at any time.
âEquipped with an independent temperature limit alarm system, it will automatically interrupt when the temperature limit is exceeded to ensure safe operation of the experiment without accidents.
âA Recorder is optional, and the printer can print and record the setting parameters and scan out the temperature and humidity change curve, and the 4~20mA standard signal.
âThe left side of the box is equipped with a test hole with a diameter of 50mm.
Refrigeration and air circulation system
âThe refrigeration machine adopts the French original "Taikang" fully enclosed compressor unit.
âUsing a multi-wing blower to provide powerful air circulation to avoid any dead spots and achieve uniform temperature distribution in the test area.
âThe air circulation outlet and return air design ensures that the wind pressure and wind speed meet the test standards, and the temperature can stabilize quickly when the door is opened.
âHeating and cooling, the system is completely independent, which can improve efficiency, reduce test costs, increase lifespan, and reduce failure rates.
