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 con¬crete 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
