The Ermenrich Reel GK40 laser meter is used to solve many construction, repair, engineering, or household tasks. It enables you to take accurate measurements within 40 meters (130ft) and to calculate volume and area. For measurements under difficult conditions, when it is impossible to position the meter correctly, there is a Pythagorean theorem feature – using indirect measurements, it helps to calculate the distance to the desired point. The device also has a bubble level, which can be used for the precise installation of the meter, and as an independent tool.

The screen displays 3 lines of data and results can be obtained in meters, feet, or inches. Previous measurements are stored in memory enough for 20 groups. Power supply: AAA batteries; a set is enough for 5,000 measurements. The auto-off function helps save battery. The battery charge indicator will tell you when to replace the batteries.

Key features:

  • Measuring distance, area, volume; Pythagorean theorem feature
  • Measuring range from 0.05 to 40 meters (0.16–130ft)
  • Horizontal bubble level
