LK-BST Argon Blowing Intelligent Control System |
Main Features：
●Adopts high-precision mass flow controllers imported original from the United States
●The entire system operates stably, is easy to operate, and can avoid operational errors.
●Settings from any flow rate to the commonly used flow rate can be completed with just 1 to 3 keystrokes.
●The system requires basically no maintenance.
●Replay historical data and analyze historical data .
