Product Applications: DZJ-300A can be widely used in building construction, engineering, installation, project supervision, deformation observation. Such as: high-rise buildings, elevators, mines, water towers, chimneys, installation of large equipment, aircraft manufacturing, shipbuilding and other industries. Features: ◆ outgoing laser brightness can be adjusted depending on the usage environment can adjust the brightness of the laser dot laser ◆ vertical quasi visible through a telescope eyepiece can be directly observed clearly visible laser surveying instruments Bowflex vertical collimator, no harm to eyes . Laser pointing effective distance of 100 meters. ◆ machine dustproof and waterproof waterproof design professional surveying and mapping equipment, completely avoid the rain caused by moisture inside the instrument, the whole dust and waterproof rating to IP54 ◆ Optional laser plummet standard preparation for the optical plummet Leica surveying instruments ranging Miriam, optional laser plummet. Laser vertical collimator use mainly to check the verticality of the vertical collimator senior surveying instruments, up and down with a laser, and then used in conjunction with laser target distance can be seen up and down the laser and exterior of the building to determine whether the vertical. Set aside 150 * 150 empty. Be sure to Zaokong. 5. After pouring carried out to vote when the upper axis measurement. Erection of control points in the vertical meter, alignment points upward projection of the laser beam, the upper target with laser receiver be accepted. And rotating vertical collimator 360 °, ... and then turn around, not in the center of the cross, then change the needle with debugging twist wire, which can specifically look for while debugging tricks, laser spot near the center of the cross half the time, turn around in half tone, and so forth can be adjusted. Similarly under the laser spot. Puri measuring laser range finder surveying instruments surveying instruments _ _ Jinke instrumentation provided by the Instrument Co., Ltd. Qingdao Branch.
