  • Description
  • product description:

    With the rapid development of China's economic construction, there are more and more high-rise and large-scale large-scale buildings and components in construction projects, and more and more units using high-strength concrete have been used. The requirements are becoming more and more urgent. For this reason, the Ministry of Housing and Urban-Rural Development of the People's Republic of China promulgated the industry standards of the People's Republic of China, the "Technical Regulations for Testing the Strength of High-Strength Concrete" and the National Metrological Verification Regulations of the People's Republic of China "Rebound Meter" (JJG817-2011). Based on the original impact kinetic energy of 2.207 Joules, our factory summarizes decades of manufacturing experience and refers to the performance and advantages of other types of rebound instruments at home and abroad. It has listened to the suggestions of experts and scholars, and through years of practice and Improved, introduced a high-strength rebound tester with 4.5 Joule impact kinetic energy for detecting radon structures and components in the range of 20 to 110 MPa.
    450 type high-strength concrete rebound tester designed and developed by our factory. The whole machine is made of high-quality, high-strength lightweight aluminum alloy using the most advanced technology. Compared with other similar products in China, it has a small size, light weight, and high stability. , The spring has a long service life, lighter operation, simpler use, durability, and is not easy to grind your hands.
