Product Description

HT225D Integrated Concrete Test Hammer OLED Display with Software to PC



Brief Introduction to the Device


HT225D Digital Rebound Apparatus has the following characteristics: integrated design, small in size; adopt non-contact optical coupler sense to realize data collection, without changing the original physical structure of mechanical rebound apparatus, in which way the optical coupler sensor has no contact nor friction with the mechanical part of rebound apparatus and thus its service life is extended.


Structure of Concrete Test Hammer

The Concrete Test Hammer is mainly composed of flip system, value-indicating system and shell component.Its structure is shown in Fig.1. The diagram shows the state that the impact hammer has finished impact in the test and the pushbutton has locked the movement, ie.retaining state of resilience value
