Thermal conductivity tester works:
Type thermal conductivity tester, using double test piece measuring device, protective hot plate group: including heating unit, cooling unit. The heating unit shall be divided into a metering unit in between and a protective unit surrounding the metering unit separated by a gap, and equipped with thermal insulation. The hot unit adopts double hot surface heaters. The cold plates are arranged symmetrically with the double hot surfaces. The thickness of the test piece sets the space for moving the cold plate. The test piece is placed vertically in two flat plates with constant temperature parallel to each other. In the steady state, the measurement part of the test piece has a constant heat flow. By measuring the one-dimensional constant heat flow Q flowing through the metering unit, the area A of the metering unit, and the temperature difference T between the cold and hot surfaces of the test piece, it can be calculated. According to the thickness of the test piece, the thermal resistance R of the test piece can be accurately calculated.

制冷系統嚴禁連續啟動，啟動間隔應大于3分鐘。
試件的測試溫度一定要低于試件的熔點溫度。
溫度過高，電源被切斷，查找原因后方可重新檢測。
試驗結束, 點 “自動檢測"鍵復位后再點“退出"鍵。
自動運行中不要點“退出" 和“手動調控"，否則實驗終止或出現失控。
制冷系統制冷劑為R十二。
系統通電時不許觸摸可能帶電部位。
本裝置在運輸搬運和移動位置時，禁止用桿子撬動底部，避免損壞 制冷系統。運輸搬運時利用頂部吊環移動或搬運。搬運時整機的傾斜角度不應超過45°角，防止損壞制冷壓縮機。
Note for thermal conductivity tester:
The grounding protection wire must be reliably grounded. Check whether the power supply voltage is normal before starting up.
Refrigeration system is strictly forbidden to start continuously. The start interval should be more than 3 minutes.
The test temperature of the test piece must be lower than the melting point of the test piece.
The temperature is too high, the power is cut off, and the cause can be checked again.
After the test, click the "Auto Detect" button to reset and then click the "Exit" button.
Do not click "Exit" and "Manual Control" during automatic operation, otherwise the experiment will be terminated or out of control.
Refrigeration system refrigerant isR十二.
Do not touch any live parts while the system is powered on.
When the device is transported and moved, it is forbidden to pry the bottom with a pole to avoid damaging the refrigeration system. Use the top ring to move or carry during transportation. The tilt angle of the whole machine should not exceed 45 ° during transportation to prevent damage to the refrigeration compressor.
