UNI-T LM50EX Laser Distance Meter (up to 50 meter)
The UNI-T LM50EX Laser Distance Meter is engineered as a high-accuracy measuring instrument designed to simplify distance measurement for construction professionals, designers, and field technicians. Built to support precise distance measurement up to 50 meters, this device replaces traditional measuring tapes and reduces measurement errors, especially in larger spaces or areas difficult to access. Its robust performance and trusted accuracy make it suitable for everyday use on job sites or detailed planning tasks.
With a large color display and a carefully arranged interface, the LM50EX provides a clear and intuitive user experience. Real-time feedback on measurements ensures users can confirm results instantly, and its rugged design stands up to regular field operation. The device also supports multiple reference points for measurement, giving flexibility in choosing the front, middle, or rear of the unit as a base reference.
Although discontinued, the LM50EX was designed with durability in mind: it supports dust and water resistance and can survive moderate drops, making it reliable in harsh construction or outdoor environments.
