Laser distance meter infrared distance measurement high precision measuring room meter measuring electronic ruler

Power supply type: AAA Battery material: ABS+LCD Measuring range: 0-100m Measuring accuracy: ±2mm Overall size (L*W*H): 12 Dust and splash proof: IP54 Laser wavelength: 21 Laser class: Class 1 / Class I Resolution/division value: 21 Laser transmission and reception double enhancement Newly designed optical lens using a new generation of aspherical lenses While ensuring accuracy, stability is greatly improved. Japan's ROHM laser is phase modulated to emit high-frequency optical signals. Phase laser ranging is usually suitable for medium and short distance measurement with an accuracy of up to millimeter level. USB lithium battery direct charging, no need to frequently replace batteries Real-time angle refresh also derives obstacle-crossing technology Electronic level sensor Measure the position of the target point, and the built-in algorithm indirectly calculates the horizontal distance and height based on the angle. Data storage, no need for paper and pen to check records at any time 30 groups of data storage Voice guidance of measurement steps and automatic data playback Real voice broadcast
