Bosch 1 600 A01 6BR level 1.2 m Aluminium, Black, Blue

The Bosch 1 600 A01 6BR Aluminium 1.2 m optical level is a precision instrument for horizontal sighting and height transfer on construction and surveying sites. Constructed with an aluminium body and a 1.2 m level staff length, this optical level delivers stable alignment, straightforward mechanical adjustment and a compact, transportable form factor weighing 1.58 kg. The instrument is intended for reliable visual leveling tasks where repeatable, clear stadia readings and robust field performance are required.

Advantages

The aluminium housing provides corrosion resistance and a lightweight balance between durability and portability, while the built-in optical system offers clear target observation for accurate height determination. Its 1.2 m length and moderate weight make it easy to mount on standard tripods and to carry between job sites. Mechanical controls are designed for fine adjustments, enabling accurate centering and repeatable measurements under typical site conditions.

Suitable for

• Establishing level references on building foundations and slabs
• Elevation checks for landscaping and site grading
• Interior and exterior alignment tasks where visual leveling is sufficient
• Surveying tasks that require a durable, portable optical instrument

Key specifications

• Material: aluminium body for improved durability and reduced weight
• Length: 1.2 m staff/instrument length suitable for common leveling setups
• Weight: approximately 1.58 kg for easy transport and tripod mounting
• Optical system: visual sighting and stadia lines for height transfer (standalone optical instrument, no electronic sensors)
• Adjustment: mechanical fine-tuning controls for centering and focusing
• Compatibility: fits standard leveling tripods and accessories used in construction and surveying

How to use

Mount the optical level on a stable tripod and secure it at working height. Roughly level the instrument using the tripod head, then perform fine centering with the mechanical adjustment screws and optical bubble or centering aid if present. Sight a graduated leveling rod or staff at the target point and read the stadia or crosshair intersection to determine elevation differences. Repeat measurements from different benchmarks as required to establish accurate height references. Transport and store the instrument in protective packaging to prevent shock and moisture exposure.

Recommendations

For consistent results, use a stable tripod and verify the instrument’s calibration periodically. Avoid exposing the optical system to prolonged moisture or abrasive dust, and clean lenses with appropriate optical cleaning supplies. When moving between locations, carry the level in a protective case and allow the instrument to acclimatize to temperature changes before critical measurements.
