Laser Level Application: DZJ-300A can be widely used in 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 spot ◆ vertical quasi visible through a telescope eyepiece laser can be directly observed clearly visible laser, no harm to the eyes. Laser point to the effective distance of 100 meters. ◆ machine dustproof and waterproof waterproof design professional surveying instruments offer, 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, optional laser plummet. Laser vertical collimator mainly to check the verticality of the top of the upper and lower 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. 150 * 150 empty reserved. Must Zaokong. 5. After pouring, the upper layer were measured axis vote. Set up in the control point on the vertical instrument alignment point upward projection of the laser beam, the laser receiver with top target was 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 tips while debugging mapping equipment rental, laser spot near the center of the cross half the time, turn circle in half tone mapping equipment, and so forth can be adjusted. Similarly under the laser spot. Leica laser rangefinder Leica DISTO D2: small partners in the base model compact, easy to carry site surveying instruments, designed for indoor applications. Addition and subtraction can be performed and the area and volume through the shortcut keys, measuring fast and very reliable. Before the measurement results can be stored 10 times. As with all Leica laser distance meters, the laser spot which is clearly visible. Even if the target is difficult to access the site, you can always find the target anchor point. Leica DISTO D2 -? You no longer need to use a tape measure to measure up!
