Detailed Product Description: | Because use of the geological compass magnetic north and south poles position south and north poles and geography are not entirely consistent, that is the magnetic meridian and geographical meridian not coincide, any point on the Earth's magnetic north to true north to the point of inconsistency vertical collimator maintenance, the angle between the two directions is called magnetic declination. East of the northern tip of the needle at a point on the earth somewhat north direction is called the East side, west side, said the West are somewhat biased. East bias is (+) Western bias is (-). Earth magnetic declination country are calculated periodically if the magnetic declination at a point known import vertical collimator, the relationship between a magnetic azimuth survey line A magnetic and true north azimuth A is A equals A magnetic subtraction magnetic bias angle. Application of this principle can be magnetic declination correction, may compass scale rotating spiral down device when the correction of the horizontal dial left or turn right (east side of the magnetic declination vertical collimator price is right WEST biased to the left), so that the chassis compass north-south line and the horizontal scale dial connection between 0--180 degree angle equal to the declination. After reading measurement correction would be true azimuth. The desired product is measured azimuth measuring the relative positional relationship between the desired product and those measured, the desired product is measured azimuth (azimuth angle refers to an angle clockwise from the meridian line of the survey). Portable laser rangefinder LDM-65 Measuring range 0.05-65 m 0.05-70 m Accuracy ± 1.5 ± 1.5 millimeters 毫米 measure meters, inches, feet, meters, inches, feet measurement history 20 group 20 group Laser class II Maximum output Power <1mW II Maximum output power <1mW Protection class IP54 dust and waterproof rating IP54 dust and waterproof rating Operating temperature 0 ℃ ~ 40 ℃ 0 ℃ ~ 40 ℃ Storage temperature -10 ℃ ~ 60 ℃ -10 ℃ ~ 60 ℃ Size 115 * 48 * 28mm 115 * 48 * 28mm Weight 135 g 135 g Sanding Total Station Total Station placed anywhere you need it most, use the program to calculate the three-dimensional coordinates of the site and set the orientation azimuth. You can use a maximum of five known points as the backsight involved in the calculation, the observations can be single or double-sided angle and distance values ??observed. Stake out point data can be input by the field, the data can also be called total station memory. Memory data can be uploaded through a computer and stored in the total station. At the same time you can view the polar coordinates, orthogonal and coordinate between stake-out offset value. MLM reference line / arc architecture axis REM staked area measuring vertical collimator price _ Branch of the Instrument (certified) _ vertical collimator provided by Qingdao Branch of the Instrument Co., Ltd. Qingdao Branch of the Instrument Co., Ltd. (www.qdjk17.com) is in Qingdao, Shandong analysis instruments leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
