The Ermenrich Reel GM100 is a laser measuring device designed for taking measurements on building sites and during renovation work. It can also be used for surveying cadastral boundaries and measuring land, as well as for any other application requiring precise measurements of an object’s linear dimensions, area or volume. The maximum measurable distance is 100 metres. The laser measure can also take angular measurements. Thanks to the Pythagorean theorem function, the instrument automatically calculates distances based on intermediate measurements. This function is particularly useful when it is not possible to position the laser so that the laser beam points in the direction you wish to measure.
The Ermenrich Reel GM100 laser distance measurer has a large LCD screen. The compact plastic body and easy access to the control buttons make this instrument simple to use, even in challenging working environments. Powered by 2 AAA batteries, the instrument is equipped with an automatic switch-off function to deactivate either just the laser or the entire instrument, in order to conserve battery life. On average, a set of batteries provides over 5,000 measurements. Depending on the mode selected, the instrument takes a single distance measurement or performs continuous measurement by scanning the surroundings. If preferred, the audible signals can be switched off.
