Laser Measure, Green Beam Laser Measuring Device with Angle Sensor, 196Ft M/In/Ft Laser Distance Measure Backlit LCD Laser Distance Meter for Pythagorean, Distance, Area and Volume Measuring

  • [BRIGHTEN GREEN BEAM] When using a traditional red beam laser measuring tape, the biggest pain point is that it is not easy to see the emitted laser light during long distance measurement. So we upgraded the red laser beam to a green laser beam. We were surprised to find that the laser brightness of the laser tape measure had increased by three times. Within the range of the laser measuring tool. Even in a bright work environment. You can also see where the laser light is at a glance..
  • [MULTIPLE MEASUREMENT MODES] This is not just a laser distance measuring tool that can measure distance. Area, volume, and Pythagorean measurement are the most basic functions. Due to the introduction of the angle sensor, this laser distance measure tool can perform more diverse measurement modes, for example, you can measure the distance from the window to the ground with one click. Or use this laser measure tool to measure the height of the second floor window without close contact..
  • [PRACTICAL FUNCTION] This laser measure can perform most measurements in 0.5 seconds. The backlit screen can be used at night. The mute function is used in quiet environments such as libraries. Data addition and subtraction calculations and 20 sets of data storage free hands from pen ....
