Reliable and EfficientAccuracy upgraded to 0.3 electronic level, accuracy: 2mm laser tape measure provides higher accuracy and faster angle measurement compared with bubble level. The electronic angle is displayed in real time, it is easier to find the horizontal direction, and the measurement result is more accurate. [Unique features] High-precision laser head assembly can quickly and accurately measure within 0.5 seconds, automatic level: only measure the hypotenuse, the horizontal distance and vertical height will be automatically calculated; automatic height: only measure 2 hypotenuses, and the vertical height will be automatic Calculation; Quick measurement: One-key automatic calculation of area and volume Practical Multiple Measurements70M Laser Ranging Accuracy: 0.2 mm/1/16 inch, Meet Your Different Needs: Automatically Calculate Area, Volume and Distance, Continuous Measurement, Pythagorean Method - 3 Points; Cover Large Area Well Home improvement laser measuring equipment, especially suitable for large areas such as apartments, buildings, real estate, factories, warehouses, buildings, industries, etc. [Unit switching & 30 data records & energy-saving design] M/FT/IN/ft+in units can be switched freely; 30 data records and calling functions, convenient for query and calculation; portable pocket size, non-slip design; 180 seconds automatic shutdown saves power electricity, it can work up to 5000 times.
