Specifications

Concrete Test Hammer is used for detecting the concrete compressive strength within the range of 10-60Mpa.

ZC3-A Concrete Test Hammer

Summary:

The meter is in accordance with technical regulation of JGJ/T23-2001,used for testing of concrete compressive strengthwithin the scope of 10-60Mpa,with the system standard energy of 2.207J,and value indicating system of pointer direct reading.Supervises the manufacturing process.

Characteristics:

Light (save 2/3 of labor compared with similar products), flexible, cheap, without power supply, easy to master, buttons difficult to fall off due to pulling process, pointer convenient for adjusting friction force, the first choice of instrument suitable for on-site nondestructive testing.
