Problems solved by technology
At present, when calibrating the constant temperature and humidity chamber, the arrangement of each point and the fixing of the temperature sensor and the humidity sensor at each point are difficult problems for those skilled in the art, and often require the technician to repeat the operation many times. Moreover, when the test point When the quantity is large, multiple operations are often required to complete the entire test calibration process. The labor intensity of the operator is high and the efficiency is low. Multiple operations also affect the accuracy of the test results.

Embodiment 2
[0093] Such as Figure 12 Shown, repeat embodiment one, have following difference: as Figure 12 As shown, A, B, C, D, E, F, G, H, I, J, K, L, M, N, O are temperature sensor detection points, A, B, C, D are humidity sensor detection points , the present embodiment is to carry out calibration detection for the constant temperature and humidity box with an internal volume greater than 2 cubic meters, and its detection points are designed as follows: the number of detection points is 15, and 15 temperature sensors and 4 humidity sensors are arranged at 15 detection points. The 15 detection points are divided into upper, middle and lower layers. The distance between the upper layer and the top surface of the constant temperature and humidity chamber = 1 / 10h~1 / 10h +5cm. The middle layer is located at the center of the height of the constant temperature and humidity chamber. The distance between the bottom surfaces of the constant temperature and humidity chamber = 1 / 10h~1 / 10h + 5c...
