Heavy duty Concrete rebound test hammer Calibration anvil

Introduction

• It’s the specialized calibration device for concrete test hammer
• This anvil is made of quality steel and tool steel, the fitting surface between anvil core and body is treated with fine grinding process, the anvil core surface hardness is HRC58-62.
• The concrete rebound test hammer average calibration value【N】=80+2, mortar average calibration value【N】=74+2.
• After 5000-8000 times operation, should rubdown the test surface, but the anvil core hardness should keep the same, otherwise it can’t use again.
• The anvil is kept in dry and dust-proof place, must avoid any collision on the test surface.
• Net weight: 49kg.
