Built-in laser reference can be used to improve its accuracy. This electronic measuring tape is reliable, accurate, precise and easy to use. Areas and volumes can be easily and conveniently calculated by simply pressing a few button Features 2 Units Display: Meter/Feet : Inch Automatic temperature compensation Laser guided measurement Data overflow indication Back-lit LCD screen Battery low indication Easy button-press calculation: "+" Auto power-off Specification Calculates area and volume Laser to target the point to which you whant to measure Auto converts feet to meters Backlight Measurement range: 0.6 to 15m (2 to 50 feet) Accuracy: 0.±5% ±1Digit Resolutions: 0.01m(1 feet) Aperture angle: approx. ±5 degrees Laser diode type: Red laser diode 650nm Power Supply: 6F22(9V)x1 Battery life: 10 hours of continuous dynamic measurement with alkaline battery Dimensions: 136x59x38mm Weight: approx. 150g (including battery) Calculation range: Length: 9999m Area: 99999m2 Volume: 99999m3 Laser beam Wattage < 1mW (mW = milliwatt) Wavelength : 650mm (nm = nanometer) Class 2 laser according to EN60825-1 Distance Meter Laser Ultrasonic à¤Ã×èͧÇÑ´ÃÐÂÐ à¤Ã×èͧÁ×ÍÇÑ´ÃÐÂÐ àÅà«ÍÃìÇÑ´ÃÐÂÐ sensor ÇÑ´ÃÐÂÐ àÅà«ÍÃìÇÑ´ÃÐÂÐ ÇÑ´ÃÐÂÐàÅà«ÍÃì ÇÑ´ÃÐÂзҧ ¡ÅéͧÇÑ´ÃÐÂÐ ÅéÍÇÑ´ÃÐÂÐ à·»ÇÑ´ÃÐÂÐ > Distance Meter à¤Ã×èèͧÇÑ´ÃÐÂÐ Distance Meter Distance Meter à¤Ã×èèͧÇÑ´ÃÐÂÐ à¤Ã×èͧÇÑ´¾×é¹·Õè à¤Ã×èͧ¤Ó¹Ç¹»ÃÔÁҵà MS-6450 à¤Ã×èͧÇÑ´ÃÐÂзҧ ÁÔàµÍÃìÇÑ´ÃÐÂзҧ à¤Ã×èͧÁ×ÍÇÑ´ÃÐÂÐ à¤Ã×èͧÁ×ÍÇÑ´ÃÐÂзҧ ÇÑ´ÃÐÂзҧ
