- Versi Bahasa Inggris (bukan bahasa China yang sulit dimengerti) - Unit dan manual bahasa Inggris, bukan versi China - Dikirim dari Jakarta dengan kardus utk keamanan produk Concrete Hammer Test atau Schmidt Hammer Test adalah metode uji kekuatan atau mutu beton yang cepat dan praktis == Description: The meter is in accordance with technical regulation of JGJ/T23-2001, used for testing of concrete compressive strength within the scope of 10-60Mpa, with the system standard energy of 2.207J, and value indicating system of pointer direct reading. Our concrete resiliometer has been approved as #34;Recommended Product for Engineering Construction #34; by the Ministry of Construction. Shanxi Institute of Building Research, who composed #34;Testing Concrete Compressive Strength Technical Regulation of JGJ/T23-2001 with Springback Method #34;, supervises the manufacturing process. II.Characteristics: Light (saving 2/3 forces compared with counterpart products), flexible, inexpensive, power-free, easy to master; the button applies stretching technics and is not easy to fall off; the pointer is easy to adjust friction. Therefore, it is the first choice applicable for on-the-spot NDT. III.Main Technical Parameter: Length of pointer: 20.0±0.2(mm) Friction of pointer: 0.65±0.15(N) Sphere semidiameter at the end of the flip rod: 25±1.0(mm) Rigidity of flip tensioned spring: 785.0±40.0(N/m) Location of flip hammer #39;s hook release: #34;100 #34; at the scale mark Work length of flip tensioned spring: 61.5.0±0.3(mm) Strike length of flip hammer: 75±0.3 Hop location of the flip hammer: #34;0 #34; at the graduated scale Fixed value of steel anvil: 80±2 (our products are controlled between 80-81) IV.Shipping A resiliometer Grindstone, Flip tension spring Buffer spring Screwdriver Instruction kalibrsi kan/iso
