Laser marking instrument (4V1H1D) laser marking series of products, based on its auto-leveling, simple, economical and practical features Puri measured imported laser range finder, is widely used in interior decoration, installation of doors, windows and cabinets, ceiling, wall charts and other professional and DIY markets, to provide horizontal and vertical alignment. Basic configuration:. LS625 host, LS703 detector, LS306 glasses, LS307 Target, lithium battery pack, 5 # hard case purpose and scope, one uses laser-line vote is widely used in construction projects among which both original The water level, theodolite scribe function. It will work with the laser line projected precise alignment of objects on the work to make the construction process more convenient, more time and more effort, while capable of high precision to ensure construction quality. 2. The use of laser-line vote is widely applicable to the construction of various construction units Leica laser rangefinder 60 meters, such as: carpentry, bricklaying, painters, electricians ... measuring tools foot tower is dedicated land surveying equipment for railways, highways, cities, mines, water conservancy, farmland capital construction, defense and other engineering topographic surveying. The factory produced a series of aluminum alloy foot tower in the timber, printing, manufacturing and so have its own unique, especially foot tower telescoping handle, the positioning structure more comfortable, strong, durable characteristics, domestic and foreign customers wide acclaim. Aluminum foot tower length: 5m * 5 shrink size: 1.24m Weight: 1.5kg aluminum foot tower length: 5m * 4 shrink size: 1.46m Weight: 1.4kg aluminum foot tower length: 3m * 3 shrink size: 1.28m Weight: 1.1kg hammer to use when testing Hammer axis should always be perpendicular to the detection surface of the concrete structure or member, slow pressure, accurate readings, fast reset. Presumed Strength of Concrete: 1, from 16 rebound values ??measured in the area, excluding the three maximum and three minimum, then the remaining 10 rebound values ??averaged. 2. Rebound non-horizontal direction and a non-member test surface, the angle should be more positive, more positive after the rebound value then the pouring surface is relatively positive. 3. The value of carbonation depth survey area and more positive rebound values ??converted value after the isolated strength concrete for each survey area. 4, made 70 meters laser rangefinder when the measured intensity values ??of the structure or member area appears less than 10.0MPa, take fcu, e <10.0MPa. fcu, min5, fcu laser rangefinder when the structure or component of the survey area is less than 10 when, fcu, e = 6, when the number of the surveyed area structure or component is not less than 10 or by batch detection, e = fcu, m-1.645 * s7, when one of the following occurs by concrete strength member survey area standard deviation batch testing time, all by a single member should detect: ① mean concrete compressive strength less than 25.0MPa, S> 4.50Mpa; ② resistance of concrete the average compressive strength of not less than 25.0MPa and not more than 60MPa, S> 5.50Mpa domestic 40 m laser rangefinder, laser rangefinder, Jinke instruments provided by the Qingdao Branch of the Instrument Co., Ltd.
