Laser rotativo Bosch GRL 300 HV Professional 300 m 635 nm (< 1 mW)

The Bosch GRL 300 HV Professional Rotary Level provides precise horizontal control with a maximum working range of 300 m and a levelling accuracy of ±0.1 mm/m. It has a self-levelling capability of ±5° (automatic) and runs up to 30 hours on a 9V NiMH battery. Compact and robust, this blue rotary level includes a 5/8" tripod thread and is intended for accurate levelling tasks in construction and surveying.

Advantages

One-button operation for each function and a self-explanatory display simplify user interaction. Automatic self-levelling in both horizontal and vertical modes enables fast setup within a ±5° range. An optional shock-warning function can be enabled or disabled to avoid levelling errors caused by shocks or vibrations, improving measurement reliability on active sites.

Suitable for

• Site levelling and grading over distances up to 300 m
• Interior and exterior construction alignment tasks
• Surveying and layout work requiring ±0.1 mm/m accuracy
• Use with tripods and rotating targets using the 5/8" thread

How to use

Mount the rotary level on a stable tripod using the 5/8" thread and switch the device on. Select the required function using the dedicated one-button controls and allow the instrument to self-level automatically within the ±5° range. If working in a vibration-prone environment, enable the shock-warning function or disable it if you need continuous operation during minor disturbances. Use a rotating target or receiver at the required distance (up to 300 m) to read the reference level.

Recommendations

For best results, mount the instrument on a solid tripod and verify the levelling before taking critical measurements. Charge or replace the 9V NiMH battery regularly to maintain the rated 30-hour runtime and avoid interruptions during surveying tasks.
