Digital Rebound Concrete Test Hammer With display for analogue
ruler and digital value
Introduction
HT-225D is an integrated digital concrete test hammer which
combines data processor and test hammer into one unit. It is widely
used for non destructive testing quality of concrete and building
materials in finished structure or prefabricated blocks. From its
rebound value, the compressive strength of concrete can be
calculated out automatically. All testing data can be stored in
memory and transferred to PC by USB cable or wireless by Blue
tooth.
Key features
High contrast OLED display
All setup can be made on site
Automatic calculating compressive strength
Automatic correction of impact direction
All data will be stored in memory
All data can be transferred to PC by USB cable or blue
tooth(optional)
Dual display for analogue ruler and digital value

Test times (test point), for each test point in each testing zone, according to Regulations, the test times are 16.
Testing zone, a test unit for testing concrete compressive strength of
structure or component, with an appropriate area no more than
0.04㎡.
Equivalent value of concrete strength in testing zone refers to the
concrete compressive strength value of the tested unit calculated
based on the average rebound value and carbonization depth of
testing zone via strength-measuring curve.
Test angle, casting surface, if the rebound apparatus is not in horizontal direction or the
tested surface is non-concrete casting side, after setting the test
angle and casting surface respectively, the apparatus can
automatically conduct angular correction and casting surface
correction of rebound value.
Carbonization depth: concrete carbonization depth is a kind of chemical corrosion of
concrete, and the process reducing concrete alkalinity is called
concrete carbonization. Carbonization depth value can be obtained
according to the relevant methods of Regulations. When input carbonization depth, only have to input a number
between 0.0mm and 6.0mm and then the apparatus can, according to
the input carbonization depth value, calculate the concrete
compressive strength value.
Test of pump concrete strength, set the curve as “national-pumping”. According to the Regulations, the apparatus calculate the corrected value of pump concrete
strength and strength-measuring curve, and the calculated concrete
compressive strength value is the strength value of pump concrete.
Strength-measuring curve, the apparatus has four optional curves in total, “national
standard-pumping”, “national standard-non pumping”, “specific curve
1” and “specific curve 2”.
