What is the difference between ultimate vacuum and max vacuum? spec says 5 Pa Ult Vac but Q&A says 20 Pa max Vac.
Answer This Question
The ultimate vacuum refers to the experimental environment, excluding the influence of various air leakage and other factors. It is marked as 5pa. In normal use, it is normal for the vacuum degree of a small pump to be below 100.
