Product Description

Digital Rebound Concrete Test Hammer With display for analogue ruler and digital value
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)

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”.
