During this process, several third temperature measuring components 35 will detect the temperature value in real time. The data collected by the several third temperature measuring components 35 is processed by the control component 40 to obtain the thermal radiation value of the product.
[0027] To prevent burns to operators during thermal resistance and thermal radiation testing, this application provides an isolation cover 50 above the test chamber 10.

The data collected by the first temperature measuring component 212, the second temperature measuring component 251 and the third temperature measuring component 35 can be processed by the PLC controller 41 and uploaded to the USB flash drive 44 for storage.

[0032] In some preferred embodiments, the first temperature measuring component 212 and the second temperature measuring component 251 of this application are contact temperature sensors, and the plurality of third temperature measuring components 35 are all infrared thermometers.
[0033] To facilitate quick operation of the lifting adjustment screw 23 by the operator, this application provides an adjustment handwheel 231 above the lifting adjustment screw 23.
