It can be used to check the system pressure, fill the system with refrigerant to vacuum, fill the system with lubricating oil and so on. Air conditioning pressure gauge is divided into low pressure gauge and high pressure gauge two pressure gauges are installed on the same table seat, the table seat has a manual valve at both ends, the lower part has three access interfaces.
The interface of the high-pressure meter is connected to the high-pressure pipe connector through a hose, the interface of the low-pressure meter is connected to the low-pressure pipe connector through a hose, and the middle interface is connected to the vacuum pump or refrigerant tank through a hose.
