This laser rangefinder uses laser technology to accurately, quickly, and easily measure distance, area, and volume. The measuring range is 40m wide, and the accuracy can reach plusmn1.5mm. In addition, the meter can use Pythagoras to indirectly measure distance or length. The meter also has a variety of functions, including continuous measurement, plus/minus function, and maximum/minimum measurement. Other main functions include 20 data memories, switchable units (meters, inches, and feet), and a backlit LCD with a multi-line display. This precise rangefinder can be used in homes, buildings, industries, houses, warehouses, etc._x005F_x000D_USB charging: comes with a USB data cable, built-in rechargeable lithium battery (200mAh), dont worry about low battery affecting the measurement_x005F_x000D_Intelligent calculation and higher accuracy: the laser rangefinder can calculate automatically and has error reporting technology. M/In/Ft units can be switched freely, the accuracy is 1/16 inches, and the measurement range can reach 98 feet (30 meters), which can meet your daily measurement needs_x005F_x000D_Wide range of applications: with multiple measurement modes such as distance/volume/area measurement, continuous measurement, and Pythagorean measurement, it is an ideal choice for home, construction, and industry, especially in rooms, apartments, buildings, real estate, factories, large areas, warehouses, etc._x005F_x000D_Portable and small: only 29g, very easy to carry, lightweight, and compact design provides a good sense of operation_x005F_x000D_The LCD with backlit, which is better visibility in low light conditions_x005F_x000D_Specifications:_x005F_x000D_Measuring range: 0.05-40m (0.16-131ft)_x005F_x000D_Material: ABS_x005F_x000D_Measuring time: 0.1-3s_x005F_x000D_Display: LCD with backlight_x005F_x000D_Accuracy: 2mm_x005F_x000D_Unit of measurement: meters/inches/feet_x005F_x000D_Laser class: Class II_x005F_x000D_Laser wavelength: 635nm_x005F_x000D_Laser output: 1mW_x005F_x000D_Waterproof and dustproof: IP54_x005F_x000D_Automatic laser shutdown: 30s_x005F_x000D_Automatic power-off: yes_x005F_x000D_Measurement reference switch: Yes_x005F_x000D_Power supply: rechargeable lithium battery (200mAh)_x005F_x000D_Working temperature: 0~40 / 32~104_x005F_x000D_Storage temperature: -20~60 / -4~140_x005F_x000D_Package included:_x005F_x000D_1 x Laser Rangefinder_x005F_x000D_1 x USB Data Cable_x005F_x000D_1 x User Manual (Chinese, English, and Japanese)_x005F_x000D_Other items not included
