Shenzhen happy letter is three-dimensional the Vm250 Series optics that limited company of science and technology develops is video the measuring instrument is a high accuracy, tall accurate hand / automatic measuring instrument. This instrument combines traditional optics and newest number advanced technique, deploy the geometry with complete function to measure software OVM randomly, have an operation handy, speed fast, function all ready, scope of application wide, economy is strong wait for an advantage, will issue the video digitlization of an observation in microscope with naked eye before, video can show observation on screen directly, and or measure directly; Provide the video and automatic tool that seek an edge, can set fixing to resemble searching sensitivity, dot, line, casing, round, arc can seek an edge quickly; And have super- go by force Mao Bian function, handlers can be found quickly accurately again wait for measure the place, can undertake metrical to the thing of irregular appearance, make handlers cast off the measurement technique that heavy in the past range estimation hand writes down, eliminated factitious error. Solving measure and 2 dimension have very high performance/price ratio in converse problem, be tool microscope and measuring projector upgrade replacement product. CNC Milling
