Ozar Lunch Laser Distance Meter 60 Meter Range. Feature:- 1.Max/min, measure 2.Distance/area/volume computation 3.Addition/subtraction operation 4.Pythagorean 5.Record the last 20 measurements. The laser distance meter is used for accurately determining the distance of an object or span without contact by way of a laser. The basic measuring principle is based on measuring the transit time of laser pulses between the laser distance meter and the object to be measured.
