1. High rigidity design ensures vacuum degree and long-term stability; 

2. Rapid flashing ability 10Pa ≤ 10s; 

3. The vacuum pressure curve of fast and slow vacuuming can be adjusted in multiple segments; 

4. Integrated molding mechanism ensures the stability of equipment operation; 

5. Multiple detection ensures accuracy, cleanliness, and stability; 

6. Pre filter+dry pump to avoid oil and gas pollution in the chamber;
