main features

■ True color GUI touch screen interface, intuitive display and easy operation

■ Power on self-test, automatic emptying of pipeline air, automatic leak alarm

■ Can detect input gas source pressure and dew point, equipment pressure and SF₆Gas density value

■ Can query the flow rate of supplementary gas within a unit time, equipped with a pressure balance device to ensure the stability of gas flow input. If it is higher than the set pressure, it will automatically release pressure protection

■ Equipped with a one-way valve to prevent gas backflow inside the equipment, ensuring absolute equipment safety

■ Equipped with rechargeable batteries and charging ports, it can provide long-term gas supply to equipment without human monitoring. For leaking equipment that cannot be repaired in a timely manner, it can be used for a long time to ensure the normal pressure inside the equipment

■ The human-machine dialogue interface is highly intelligent, displaying various air supply pipelines and solenoid valves, as well as pressure and dew point values in graphical form. The operation is simple, and the air supply operation can be completed with just a light tap
