levelling device AP-228 Pentax

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 holes 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 fall down , 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 Levelling  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 - February, the Saint, Tarzan) A device Levelling  (new) from a few part has been formed: Telescope Balance upload Page calibrate the angle of the horizontal Screw setCompressor ( in some models) The Japanese company "Pentax" (Pentax) is one of these companies with great history and reputable in the field of production of imaging equipment is engineered, and its products have always been of the opinion quality others, has been and is. One of the models produced by this company, the camera Levelling  model AP-228 is. Lens this camera with a diameter of 30 mm has a magnification equal to 28 times and has been the lowest so that you can picture, clear and transparent in the camera view. equivalent to 40 cm. This device has a system of internal within themselves that if the angle of the 15 minutes, the alignment outside the tradition. continues the axis of the Gameboy camera in a state of balance is located. You elevation that measurement you to the true meaning of right and correct will be. An error that this device is in benchmarking (measure the difference in height) to the length of 1 km and went back with that encounter, only to the extent of 1.5 MM is very good accuracy for this device will be. This device good resistance against the penetration of water and dust from your show. Camera Levelling  ., the category of instruments measure the difference in height, and are special only to that purpose made and are marketed. The importance of measuring the height difference to the extent that the company is many years away, has been to build and develop this category of tools of measurement have been. Company Pentax of the producers called and reputed equipments, camera, etc. lonār and its accessories. The company's products, great diversity, and in addition to workers branch mapping, engineering, etc. those with the camera work and the world of imaging, their activities, etc. with the products of this company are familiar.
