石屎槍 | 石屎試力槍

HT-225 石屎槍，廣泛用於混凝土硬度測試，亦稱混凝土回彈錘，測量時無損材質表面，適用於硬度高的材質、岩石和建築材料，而且操控簡單，儀器尺寸精細，易於使用。

HT-225 is a hardness tester or concrete test hammer, also called a concrete rebound hammer, Schmidt hammer or Swiss hammer, used for non-destructive measurements of surface hardness and compression strength. Suitable for use with concrete, rock and building materials, this manufacturer-calibrated manual rebound hammer is economical, practical and easy to use.
