TOMLIN Cement Hardness Tester

Description

The TOMLIN Cement Hardness Tester is designed to meet JGJ/T23-2001 technical standards, utilizing the HX-225 mechanism to accurately measure cement hardness and concrete compressive strength within a range of 20–60 MPa. With a standard energy of 2.207 J, it employs a pointer-based direct reading system to deliver precise measurements. Compliant with the GB9138-88 and JJG817-1993 national metrological verification standards, this tester is officially recognized by the China Construction Science Research Institute. It is a perfect solution for structural testing in general construction, bridges, and various components like plates, beams, columns, and more.
