Overall conclusion:
The main technical indicators of the temperature equipment meet the corresponding technical requirements, meet the factory technical standards, and are allowed to leave the factory.
Additional information:
1. When the measuring body is in the air, the machine is running normally under no-load condition.
2. The position of each temperature detection point, the upper test point is 10cm away from the top wall, the lower test point is 10cm away from the bottom wall, the upper and lower points are 10cm away from the box wall, the center point, and the humidity measurement point is the geometric center point of the box work space.
3. Each test point is the highest temperature point of the equipment, the intermediate temperature point and the lowest temperature point for performance testing. The humidity measurement is the humidity of the intermediate temperature.
4. The above measured data is the data measured after the temperature reaches the set value for the first time and stabilized for 30 minutes, and is recorded continuously for 15 times. That is, it is measured once every 2 minutes, and 15 times are measured.
