Problems solved by technology

[0002] The heating source of the existing detection device is often vacant, which is easy to cause heat loss and uneven temperature in the heating area, and at the same time increases energy consumption and wastes resources. Moreover, the existing single heating method increases the difficulty of temperature controllability. The accuracy of the data is low, and it is often necessary to repeat the detection many times to obtain more accurate data. At the same time, the existing detection device can only detect the time between two or three temperature differences at a fixed distance position, and the detection function is single. , the fire resistance test also needs another instrument for testing, and the data obtained by the sample test is not comprehensive
