Vakuudetasot
Vakuudetasot, often translated as vacuum levels, refers to the degree of vacuum achieved in a space. A vacuum is a state where the pressure is significantly lower than atmospheric pressure. The "level" indicates how close to a perfect vacuum the space is. Perfect vacuum, a theoretical state, has zero pressure. In practice, true vacuums are unattainable. Instead, we categorize different ranges of vacuum based on the remaining pressure.
These levels are crucial in many scientific and industrial applications. For instance, high vacuum is essential
