Brief Description; IntroductionThis professional rangefinder uses laser technology to measure distance, area and volume accurately, quickly and easily. It has a wide measurement range of 0.05 to 40m (131ft) and a particularly high accuracy of 2mm. Additionally, the meter can indirectly measure distance or length using the Pythagorean theorem when direct measurement is not feasible. The meter also has multiple functions, including continuous measurement, plus/minus functions, and max/min measurements. Other key features include 100 data memory, switchable units (meters, inches and feet) and a backlit LCD with multi-line display. The included bubble level can be used as a spirit level tool. Laser rangefinders have a wide range of applications in construction and industry. It is very useful and convenient to accurately measure distances, areas and volumes, especially in large areas such as rooms, apartments, buildings, real estate, factories, warehouses, gardens, roads, infrastructure, etc. featureWide measurement range from 0.05 to 40mhigh accuracyQuickly measure distances, areas and volumesAutomatic calculation of area and volumePythagorean Indirect MeasurementContinuous measurementMin/Max distance trackingAdd and subtract measurements easilySwitchable between meters (m), inches (in), feet (ft) Easy aiming with bright laser pointerLarge LCD with backlightDisplay lighting and multi-line displays100 data recordsSelf-calibrating -9mm to 9mmBubble level as a spirit level toolAutocorrect and error reporting technologylow battery indicatorAuto/manual shutdown functionSpecificationMeasuring range: 0.05 to 40m (0.16 to 131ft) Accuracy: 2mm (0.08 inches) Laser Class: Class IILaser Type: 635nm, Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
