levelling device STAL 1132 Stonex

Including devices primary used to align the positioning level of water (Water Level) is by the ancient Iranians to be. This alignment with. the tube of the straw has been that the middle of it hole and per head it Hole small, attached to a rope will. Two people each head, the rope on a piece of wooden graded keep saying, then people in third bowl from the middle hole with water Reed  , if the water from each of the holes of the two head to the extent of inequality and women to wear perfume, head tanabi that more high was located, so the bottom of the  to  identical from the two head drain . The size of the head the wood and place the rope height difference between the two was spot on.Day of the alignment of the glass that holds the bubble was use was . In other countries the alignment of the glass has a curvature, a certain was, that in the event of horizontal, being the balance of the bubble perfectly in the middle of the alignment of the incident . In later years, the ... factory, manufacturer, fixtures, mapping, embedding one or two numbers align on the side of the camera, it possible to provide believed that when the bubbles align in the middle is the axis of the cue on the camera is also horizontal crafted. Thus, by moving the side axis, the sign on a horizontal surface in space is created. With the help of this axis height difference between two points the measurement is. Thus, alignment of the optics(Optical Level) was produced. The balance on the tripod, and install with three screws set the axis indication on the camera for horizontal incident and move side camera-page horizontal in the space made was.Devices leveling just to be able to create a square, horizontal, in space were, and to determine the elevation difference of the points from the pieces, graded the wood that the same indicators are used was.Adding a page, a graded horizontal to the camera, the possibility of measuring the horizontal angles between the two stretches on the ground to this vehicle was added. (Source the book the basics of mapping - Avalanche Saint NIA)is a device leveling (new) from a few part has been formed: telescope alignment page calibrate the angle of the horizontal screw set Compressor ( in some models)leveling automatic or to the name of the approach, in it. niuo, etc. one of the easiest and, of course, the most widely used camera mapping direction of the measurement height and the height difference between the points with a careless top. Italian company STONEX , producer and global types of equipment, surveying and measurement, including camera نیوو (leveling automatic) is. Model STAL 1132 of the company's European, with a magnification of 32 equality, lens, object, etc. a vivid picture of the target with high detail display.Also, by having the system Compressor powerful that the range of 15 minutes any deviation device corrects the ... the user, despite the wind blowing or the ground shake also always Video clear and no vibration, can see the track. This leveling professional in 1 km benchmarking for sweep, an error equal to 1.5 mm, it will be found that an acceptable accuracy to be expected and it can be used in all projects, educational, construction, benchmarking and ... benefit. Most small distance, a reliable resolution STAL 1132, equivalent to 0.4 meters to Infinity. It is worth noting that the threaded connection of these goods to the tripod has a size of 5/8 inch (large) is. The weight of this device, as well as for the net, 1.2 kg.
