Product details: Distance range 15-1800m range error ± 1m ± 0.1% Power 6F22 (9V) exit pupil diameter 3.6mm exit pupil distance 13.5mm Weight 425g Dimensions 60x145x145mm Effective objective lens diameter 25mm Product parameters Distance range: 15- 1800m distance mode: Semiconductor laser ranging (harmless to eyes) Ranging Error: ± 1m ± 0.1% Ranging Display: LCD display field of view Effective objective lens diameter: 25mm Coating: Multi-Coated Exit Pupil Diameter: 3.6mm Exit pupil distance: 13.5mm Focus mode: eyepiece focusing Telescope magnification: 7x The vision at 1000m: 140m (FOV 8 °) Ranging Mode: RAIN; RELF;> 150; Standard Mode Power: 6F22 (9V) Appearance: Black Dimensions: 60x145x145mm Weight: 425g Tripod thread: 1/4 "× 6 gift: GC3007 ultrasonic range finder - indoor measurements, decoration measurement, the best place to buy a house area of ??ultrasonic distance measurement is laser rangefinder Following Another new mode appears ranging, its principle is to use the machine to detect the ultrasonic waves to return to the time difference between the calculated distance between the machine and obstacles, ranging in both convenient and fast characteristics, it is possible to obtain accurate distance data, such as shop ultrasonic range finder, ranging in scope 0.6-18m of error is no more than 4cm, with a very high accuracy, accuracy is not required in some special occasions particularly high, such as measuring the hair Embryo room area, roof height, it is particularly convenient and practical, but with respect to moving a thousand dollars of expensive laser range finder, ultrasonic range finder inevitably has some limitations: 1. ultrasonic range finder can not within the measurement range to mm level obtain accurate test data, ultrasonic range finder resolution of cm. The rangefinder error within the measurement range will be 1-4cm, fully able to meet the application requirements of non-professional occasions ; if it is too demanding professional precision engineering survey person, or always look at things with a harsh critical customers, please stay away from this range finder, do not expect less than 100 dollars of ultrasonic range finder can be achieved at least more than 1000, as many as tens of thousands of precision laser range finder; 2. ultrasonic range finder ultrasonic ranging media, thus requiring not much in the transmit path acoustic obstacles, obstacles will affect the sound wave The transmission and reflection and affect the measurement accuracy of the spatial variation of the path, the more obstacles, the more inaccurate data, such as an open hall from somewhere the beginning of the end walls of the narrow corridor alignment hall opening start somewhere measurement, data will surprise you, because the walls of the hall and corridors corner facing the acoustic interference caused a great deal of reflection, see page illustrated below; The ultrasonic range finder for relatively flat and launched a large area The measured wall will achieve a very high precision, but if there is a large bump ups and downs measured the wall or by a plurality of planar composition, will lead to considerable error, because the reflected sound waves such walls would cause great Interference; The ultrasonic range finder is mainly used for indoor, outdoor If it is used, select no wind and atmospheric conditions better weather, ultrasonic range finder does not apply to windy environment, because the wind would sound waves propagation speed and direction cause interference. This product is made of high quality ultrasonic sensor refined specifically for ultrasonic ranging, detection range of 0.6--18 meters, and can calculate the area, volume and other parameters, measured values ??can be stored. This product is a high-tech products, the majority of products are exported to European markets. Features: * use of ultrasound for certain vertical distance from a point to a surface for accurate measurements. * You can select metric or imperial measurements, calculation, or convert between the two formats. * Internal automatic temperature compensation, measure the distance from the ambient temperature. * Available for guiding the laser measurement, in order to more accurately measure. * Auto-off function Technical parameters: 1. Range: 0.6-18.0m 2. Accuracy: ± (0.1m + 0.5% × distance) 3. Power: 9V battery 4. Resolution: 1cm 5. Power: 0.02W 6. Temperature compensation: 0 ~ 38 ℃
