Introduction
HT-225DS Digital Rebound Apparatus is a product designed according
to Technical Regulations for Concrete Compressive Strength Test by
Rebound Method (JGJ/T23-2001) (hereinafter referred to as
Regulations) and developed in order to meet actual requirements for
the field test of concrete compressive strength, applicable to the
non-destructive testing of common concrete compressive strength in
all kinds of construction engineering. It is specifically
applicable to the on-site quality sampling inspection by
Engineering Quality Supervision Institutions and Supervising Units,
for the compressive strength test result of the inspected concrete
structure can be got immediately; when the Construction Quality
Testing Institution carries out on-site test for real construction
objects, it can further reflect the fairness, scientificity and
accuracy of the
test, greatly improving the working efficiency of testing, data
processing and inspection report formation.
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．
Key feature
High contrast OLED display
All setup can be made on site
Automatic calculating compressive strength
Automatic correc tion of impact direction
All data will be stored in memor y
All data can be transferred to PC by USB cable or Bluetooth
Dual display for analogue ruler and digital value
