Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below with reference to embodiment and
Attached drawing is described in further detail the utility model product.
As shown in Figs. 1-5, a kind of constant temperature and moisture test machine, the testing machine include cabinet, include temperature in the cabinet
Sensor, humidity sensor, dehumidifier, humidifier, heater, refrigerator, motor and PCB control system；The temperature sensing
Device, the humidity sensor, the dehumidifier, the humidifier, the heater, the refrigerator and the motor with
The connection of PCB control system；
It is characterized by: the cabinet further includes upper port, lower port, upper pipeline, lower pipeline and main pipeline, the upper gas
Mouth is connect with one end of the upper pipeline, and the lower port is connect with one end of the lower pipeline, the other end of the upper pipeline
Connect after being connected with the other end of the lower pipeline with the main pipeline, the other end of the upper pipeline and the lower pipeline it is another
