The 9-point temperature test of Yuanyao industrial oven is a test method used to detect the uniformity and accuracy of the temperature inside the oven. It has important applications in oven calibration, performance evaluation, etc. The following is a detailed introduction from the aspects of test point selection, test method, test basis and significance:
Test point selection: Select 9 specific locations inside the oven for temperature measurement. Among them, 8 points are located at a distance of 10cm (error range ±5cm) from the geometric surface of the 8 corners of the oven, and the 9th point is located at the center of the oven.
Test method: Connect the 9 test points of the oven with a temperature recorder, and set the oven temperature to different temperature levels such as 100 degrees, 150 degrees, 200 degrees, 300 degrees. According to the operation method of the temperature recorder, set the parameters of each point of the temperature recorder. After the temperature of the oven reaches stability, record the actual temperature values of the 9 test points of the oven at different set temperatures.
Test basis: The calibration test is mainly based on JJF1101-2003 "Environmental Test Equipment Temperature Calibration Specifications", the calibration cycle is one year, the environment requires a temperature range of 18-28℃, a humidity range of 35﹪-75﹪, and the acceptance range of some factories is +/-5%.
Test significance: Through the temperature test of these 9 points, we can fully understand the actual temperature conditions at different locations inside the oven at different set temperatures, and evaluate the uniformity and accuracy of the oven temperature.
This helps to determine whether there are areas with large temperature differences in the oven, so that when using the oven, the industrial products and materials can be placed reasonably according to the actual temperature distribution to obtain better baking results. At the same time, it can also detect whether the oven's temperature control system is working properly, providing a basis for the calibration and maintenance of the oven.
