Laser vertical collimator performance indicators: Effective range: ≥120m (daytime) ≥250m (night) exit power: 1mw point under the minimum focus distance: 0.5m Objective lens aperture: 36mm Magnification: 25X Field: 1 ° 50 'imaging : As Minimum sight distance: 0.8m wavelength: 635nm Power: 2 AA alkaline batteries wavelength: 635nm spot diameter: ≤3mm / 50m FOV: 5 ° Imaging: Just as Magnification: 3X Focus Range: 0.5 ~ ∞ WTC-H Concrete Test Hammer for nondestructive detection structure and concrete compressive strength of the instrument. The surface hardness of concrete structures by detecting the estimated strength of concrete structures. The instrument uses value driven bomb shells hit the hammer spring, shells hit one end touching the other end face detection test surfaces of concrete structures is the fillip bar, resulting in resilience. In the role of resilience, playing hammer push pointer sliders are moved rangefinder, in order to gain pointer readings. Instruments reasonable structure, easy to correct price range finder, and maintenance. small size, light weight, but to carry suitable for field testing of laser marking instrument (4V1H1D) laser marking series of products, based on its auto-leveling, simple, economical and practical ultrasonic range finder, etc., are 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 datum. Basic configuration: LS625 host, LS703 detector, LS306 glasses, LS307 Target, lithium battery pack, 5 # hard case purpose and scope, 1. Uses laser line projectors are widely used in construction projects among which both the original The water level, theodolite crossed function. It will work with the laser line projected on the precise alignment of the work object, so that the construction process more convenient, more time and more effort, while capable of high accuracy to ensure construction quality. 2. Use the range of the laser line projectors are widely used in various construction unit construction projects, such as: carpenters, bricklayers, painters, electricians ... handheld laser rangefinder, rangefinder, Qingdao Branch of the Instrument Branch of the Instrument Limited.
