LANGRY Penetration Mortar Strength Tester SJY-800B is suitable for masonry mortar strength testing. The penetration method is based on the relationship between the depth of nail penetration into the mortar and the compressive strength of the mortar, using the lever force method, compressing the working spring to load, storing potential energy, and instantaneously penetrating the nail into the mortar. A field detection method that measures the penetration depth of the nail and converts the strength by combining it with the relevant strength measurement curve.

• Simplifies operation and improves efficiency with instant energy release.
• Provides precise strength readings using standardized curves.
• Quickly and conveniently assesses strength without damaging components.
• Widely used in construction and engineering testing.
• The body adopts a lightweight design concept, making it more portable and easier to use.
• The clip uses a six-petal design for multi-angle clamping, making it more convenient to install the test nail.
• The innovative lever force application design simplifies the operation steps and improves work efficiency.
• High-strength test nails and nail gauges are included, made from high-strength materials, making the test nails more durable.

Standards

• ASTM C803 / C803M - 03(2010)
