The Bosch GRL 400 H is a professional-grade rotary laser level designed for precise leveling and alignment tasks in various construction and surveying applications. This article will delve into the features and capabilities of the Bosch GRL 400 H and compare it with other rotary laser levels available in the market.
The Bosch GRL 400 H is known for its ease of use, robust design, and reliable performance. It features a self-leveling system with a range of ± 8% (± 5°), allowing it to adapt to different terrain conditions. The laser operates at a rotation speed of 600 rpm and has a working range of up to 20 meters without a receiver, extending to 400 meters with a compatible receiver like the LR 1.
- Easy Operation: The GRL 400 H boasts a simple one-button operation, making it user-friendly for professionals and DIY enthusiasts alike.
- Self-Leveling: It automatically levels itself within a range of ± 8% (± 5°), ensuring accurate horizontal alignment.
- Dust and Splash Protection: The IP 56 rating provides robust protection against dust and water, making it suitable for harsh outdoor environments.
- Long Range: With a receiver, the laser can cover distances up to 400 meters, making it ideal for large-scale projects.
- Accuracy: It offers an accuracy of ± 2.4 mm at 30 meters, ensuring precise leveling results.
The Bosch GRL4000-90CHVGK is another high-end model from Bosch, offering advanced features like Bluetooth connectivity and a green laser beam that is up to four times brighter than standard red beams. It has a longer range of up to 4,000 feet with a receiver and includes features like dual dial-in slope for grading applications.
