Digital penetrometer SJY-1000B

manualfor concrete

Langry penetration concrete strength tester is suitable for masonry concrete strength test. The penetration method is based on the correlation between the penetration depth of the nail into the concrete and the compressive strength of the concrete, using the lever force method, compressing the working spring to load, storing potential energy, and instantaneously penetrating the measuring nail into the concrete. A field detection method that converts the intensity by combining the penetration depth with the relevant intensity measurement curve. Main Feature High quality raw materials Imported high-quality springs are more fatigue-resistant, aluminum alloy spring seat snap ring assembly. Improved pointer design, easy to adjust friction and more stable. Abrasion resistance of super-hard 6061aluminum alloy casing, and the button is not easy to fall off by stretching process. User friendly design Silicone bracket for soft hand protection, more comfortable rebound operation. Beautiful label and ruler are easy to read, and the hard oxidation treatment of the parts is beautiful and durable. Multiple original imported dust-proof components, cleaner move-ment and longermaintenance period.
