Range of 20-60mpa Portable Concrete Hardness Tester for Concrete Compressive Strength
The Cement Hardness Tester apply the rebound hammer method, also commonly referred to the Schmidt Hammer is a test to check the impact strength of a concrete substrate.
This hammer has a piston that is engaged easily by the user, then when pushed on to the concrete “fires”. The scale on the hammer then produces a reading in PSI (pounds per square inch) of the tested area. Low readings could signify faulty strength concrete or hollow spots. These need to be addressed prior to doing any surface prep.
Once a contractor begins the surface preparation, it has been determined they accept the slab “as is” and are responsible for completing their proposed Scope of Work.
The Cement Hardness Tester is used to test mpa within the scope of the concrete compressive strength, the system standard energy for 2.207J, and value system as pointer direct reading type medium, the cement hardness tester execute GB9138-88 and JJG817-1993 national metrological verification code standards, by the China construction science research institute producer.
Cement hardness tester is suitable for testing the general construction, Bridges and various propose member (plate and beam, column, bridge) strength.
Center guide adopts imported materials, high accuracy, resistance to wear and tear.
Shell is made of super hard aluminum, avoid on-site damage equipment, prolong service life.
Pointer block the external type spring coil structure, convenient for friction adjustment, and can guarantee pointer shaft and pointer slider friction force uniform, to ensure the accuracy of the instrument.
Advanced low power consumption power management function, can install screen backlight, voice volume, automatic dormancy, and has the automatic shutdown function.
