Two quick-change male connectors 10 are connected to quick-change female connectors 5-2 corresponding to two adjacent detection ports 103. The pressure difference between two adjacent detection ports 103 is detected sequentially. If all detection values ​​are lower than the set value, it indicates that product 100 meets the production requirements. If one pressure difference detection value exceeds the set value, it indicates that product 100 does not meet the production requirements.

[0064] In summary, this pressure monitoring device has a simple structure and can detect whether the internal channels of the heat exchanger meet production requirements through a differential pressure detection component, thereby reducing testing costs.
