iDili HT-225 Resiliometer Concrete Rebound Hammer Tester 10-60Mpa Concrete Rebound Test Schmidt Hammer

iDili HT-225 Resiliometer Concrete Rebound Hammer Tester 10-60Mpa Concrete Rebound Test Schmidt Hammer

• The test hammer submit to standard of GB/T9138-1988 and JJG817-93 and JGJ/T23-2011 and ASTM C 805. HT-225 concrete test hammer is applied to test the compressive strength of building concrete components, bridge and so on.
• The center guide rod is made of high-quality materials, high precision and wear-resistant.
• The shell is made of polymer composite material, which has excellent impact strength, creep resistance, heat resistance, cold resistance, electrical insulation and other characteristics. This material can avoid damage to the instrument during field operations and prolong its life. service life.
• The pointer slider adopts an external spring coil structure, which is not only convenient for friction adjustment, but also can ensure the uniform friction between the pointer shaft and the pointer slider to ensure the accuracy of the instrument.
• The rebound hammer determines the average rebound value Rm on the steel anvil: 80±2
