An engineering level is a precise optical instrument used for measuring height differentials and establishing horizontal lines in construction and measurement of relative levels. Survey lab (SCEE) NICE has digital and auto levels.
A digital level is a modern surveying instrument that utilizes digital technology for highly accurate measurements of height differentials and slopes in construction and surveying projects.
An auto level, also known as an automatic level, is a surveying instrument equipped with a compensator mechanism that automatically maintains a horizontal line of sight, allowing for precise leveling operations. The following instruments are available:

• 10 x PENTEX AUTO LEVEL AP 281
• 5 x LEICA SPRINTER 100
• 1 x RUGBY 100 LR
• 1 x CHINA B 20 AUTO LEVEL
