AI Technical Summary

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.
