Apart from the usual area and volume calculation as well as simple Pythagoras for indirect height measurement, the GLM 150 Professional provides seven other measurement functions: Combined Pythagoras for partial height measurement, double Pythagoras for convenient tripod measurements and height calculations at inaccessible positions, trapezoid function for measuring roof inclinations, timer function for precise measuring with tripod or from difficult measuring points, as well as a surveying function to mark recurring distances. The Minimum-Maximum function can be used in combination with all other measurements.
Up to ten times faster than with a folding rule and pocket calculator, the wall area function determines the total area of several walls. With a consistent room height, it is sufficient to determine the wall height once and then measure the wall lengths in succession. The areas are then added up automatically and quickly. The device can also add new measured values to or subtract them from stored measured values.
The user sets all the functions on the clearly arranged button pad marked with intuitive symbols. The measurement results and device settings are easy to read on the large illuminated four-line display. The GLM 150 Professional automatically saves the last 30 measurements. The folding multifunction measuring pin ensures flexibility when measuring inaccessible positions or outer edges.
The reception optics of the rangefinder with a particularly large glass lens also pick up very weak reflected light signals. For the first time, the lens and reception diode are mounted on a support made of sintered ceramics. This keeps the optical system constant even in the event of large temperature fluctuations and different humidity influences, ensuring the highest precision over the entire service life of the device. The glass lens is also considerably more resistant to scratches than plastic lenses.
For reliable work on the construction site, the laser rangefinder and its battery compartment are protected against dust and splashes according to IP 54. Rubberized edged and corners make it rugged, reliably protecting the device if it is dropped.
