HT-225B concrete test hammer High-quality mechanical high polymer material shell portable strength | Инструменты

Concrete Test Hammer HT-225B is the latest development and production of high-quality mechanical type hammer. 1, stylish lightweight shell Shell instrument with a polymer composite material has excellent impact strength. Because this material has excellent impact strength, resistance, is widely used in aviation, construction, machinery and other fields, creep resistance, heat resistance, cold resistance, electrical insulation and so on. 2, the new generation of Hammer has a long service life Every important component HT-225B Hammer has been done to improve the system technology and strict quality control processes greatly improve the overall performance of Hammer, extending the life cycle and equipment maintenance. 3, shell color coating - flexible rubber paint Viscoelastic flexible rubber paint spray housing has to structural vibration and noise damping, and has a special soft touch and high elastic surface feel; impact resistance, recoverability, feel soft, smooth and uniform film resistance Strong chemical resistance. Explanation     In line with JJG817-2011 "Hammer" test procedures and JGJ / T23-2011 technical specification. HT-225B-type concrete Hammer suitable for detecting general building components, bridges and all kinds of Quan strength member (plates, beams, columns, bridge) is.   Feature     1) Center guide rod using imported materials, high precision, wear-resistant; 2) housing using polymer composite materials, experts feel good elasticity, prevent damage instrument field operations, to extend the service life; 3) Pointer slider using external coils structure, both for the friction adjustment, but also to ensure uniformity pointer shaft and pointer slider friction, to ensure accuracy of the instrument. Relatively high accuracy peer products, quality and cheap, long service life.   Technical parameters     Strength range: 10-60Mpa Nominal impact energy: 2.207J (0.225Kgf.m) Shells hit extension spring stretched length: 75 ± 0.3mm Pointer slider static friction: 0.65 ± 0.15N Fillip bar spherical radius of curvature SR: 25mm ± 1mm Hammer on a steel anvil calibration average rebound value Rm: 80 ± 2 Dimensions: Φ54 × 278mm Weight: about 1Kg
