Applications
◆This product is suitable for testing equipment required in the fields of aviation, automobiles, home appliances, scientific research, etc. It is used to test and determine the parameters of electrical, electronic and other products and materials after high temperature, low temperature, humidity heat or constant temperature environment changes and performance.
Box structure
◆The box body is processed by CNC machine tools, with beautiful and elegant appearance, and adopts non-reactive handles, which are easy to operate.
◆The inner tank of the box is made of imported high-grade stainless steel (SUS304) mirror panel argon arc welding, and the outer shell of the box is made of A3 steel plate with plastic spraying.
◆Adopt (7.0-inch) super large screen, easy to operate the screen, and easy to program edit.
◆The large observation window is equipped with a lighting lamp to keep the inside of the box bright, and double-layer glass is used to clearly observe the situation inside the box at any time.
◆With an independent temperature limit alarm system, it will be automatically interrupted when the temperature exceeds the limit, so as to ensure the safe operation of the experiment without accidents.
◆Optional Recorder, the printer can print and record the set parameters and scan out the temperature and humidity change curve, 4 ~ 20mA standard signal.
◆The test hole with a diameter of 50mm is equipped on the left side of the cabinet.
Refrigeration and air circulation system
◆Refrigerator adopts French original "Taikang" fully enclosed compressor unit.
◆Multi-blade air blower is used for strong air circulation, avoiding any dead angle, and can make the temperature distribution in the test area even.
◆The wind circuit is designed for air circulation and air return. The wind pressure and wind speed are in line with the test standards, and it can make the temperature stabilize quickly when the door is opened.
◆Heating up, cooling down, the system is completely independent and effective, reducing test costs, increasing life, and reducing failure rates.
