Automatic Level
An Auto-Level is a Professional Levelling Tool used by Contractors, Builders, Land Surveying Professionals, or the Engineer who demands accurate levelling every time. Magnetic damping level is widely used in geodetic instruments, used for national measurement standards, building surveying and large machine installation.
This product can meet a variety of construction engineering and measurement requirements, has automatic compensation function, and can greatly improve the working efficiency and avoid the error rate.
- Chinese patent, excellent shockproof function.
- Excellent sealed structure for using any weather.
- Exclusive closed magnetic field, magnetically-dampened compensator.
- Friction-braked rotation and endless horizontal drive.
- Prism for viewing circular level.
