Same summary
The Uni-T LM40Mi laser distance meter is designed for users who frequently perform indoor and outdoor measurements and need a range of up to 50 meters. With a built-in lithium-ion battery, it is suitable for more intensive or regular use, where fast charging and long autonomy are important.
