Optical Levels, also known as dumpy levels or auto levels, are traditional surveying and levelling instruments designed to establish accurate horizontal lines of sight over medium to long distances. They are widely used in construction, civil engineering, and landscaping for setting out levels and checking elevations.
Key Characteristics:
High Accuracy: Provides precise levelling results, typically within ±1 mm at 30 m.
Magnification: Equipped with telescopic lenses (commonly 20× to 32×) for sharp, clear target views.
Automatic Compensator: Ensures stable line of sight by correcting minor vibrations and movements.
Durable Build: Robust housing with dust- and splash-proof protection for reliable outdoor use.
Tripod Compatible: Standard mounting threads for use with surveying tripods and measuring rods.
Common Uses:
Construction & Civil Engineering: Setting out building foundations, drainage lines, and roadworks.
Landscaping: Establishing gradients, slopes, and contours for outdoor projects.
Surveying: Checking elevations and transferring levels across distances with accuracy.
