Optical Leveling Instrument Bosch 1600A016BN 25 m range

Bosch 1600A016BN is an optical leveling instrument with a 25 m range designed for horizontal alignment and height transfer tasks. The instrument provides clear, magnified sighting through an optical telescope and a graduated leveling vial to support accurate alignment on small and medium-sized jobs. Its compact design and manual leveling mechanism make it suitable for construction, interior installation and surveying tasks where a limited working range of up to 25 metres is sufficient.

Advantages

The optical level delivers reliable line-of-sight accuracy without electronic components, ensuring consistent performance in environments where power is not available. Its 25 m working range is optimized for indoor and site tasks such as floor leveling, fixture installation and short-distance elevation checks. The robust housing and simple tripod mount provide stable setup and repeatable measurements, while the optical system gives clear target acquisition for precise readings.

Suitable for

• Interior leveling and floor screed alignment
• Setting heights for plumbing and electrical fixtures
• Site layout and short-range surveying
• Checking elevations during finishing work

Key specifications

• Optical telescope with magnification suitable for close to medium distances
• Working range: up to 25 m for reliable sighting and alignment
• Manual leveling using built-in leveling vial or screw adjustments
• Tripod mount compatible with standard survey tripods for stable setup
• Robust housing designed for on-site handling and transport

How to use

Mount the optical level on a stable tripod and roughly level the instrument using the tripod head. Use the built-in leveling vial and fine adjustment screws to bring the bubble to center, ensuring the telescope is horizontally aligned. Aim the telescope at the target staff or reference point, focus the optics for a sharp image, and read the staff or alignment mark. Repeat leveling checks after moving the tripod to a new position to maintain accuracy across measurements.

Usage recommendations

For best results, use the instrument within its 25 m effective range and avoid extreme vibrations or unstable surfaces. Calibrate or verify the optical alignment before critical measurements, and protect the optics and leveling vial from dust and moisture when storing or transporting the unit.
