The Spectra Physics 124562 AL24M is a professional leveling instrument designed for precision measurements in construction, surveying, and engineering. This high-quality optical level features a 24x magnifying telescope with exceptional clarity and light transmission for accurate readings up to 100 meters away. A reliable automatic compensator ensures leveling accuracy of 0.5 mm per kilometer, even under challenging field conditions. The robust aluminum housing protects against dust and moisture, weighing 2.1 kg for optimal portability and stability during extended use. The AL24M model includes a horizontal circle with 1-degree divisions for easy angle measurements and comes with a sturdy wooden carrying case. The tripod thread connection complies with the 5/8-inch standard and is compatible with most professional surveying tripods. The effective temperature range of -20°C to +50°C allows for use in various climate conditions. The eyepiece offers adjustable diopter settings for individual vision requirements, while the objective lens is equipped with a sunshade to reduce glare and improve visibility in bright sunlight. As a successor to earlier AL series instruments, this leveling tool continues Spectra Physics' reputation for reliability and measurement precision. Its balanced design minimizes user fatigue during prolonged observations, and all optical surfaces feature multiple coatings to enhance contrast and reduce internal reflections. This leveling instrument provides a practical solution for professionals needing reliable height measurements with ease of use and minimal maintenance.
