Digital rebound hammer used for testing the compressive strength of ordinary concrete in the range of 10 to 70 N/mm² (1'450 to 10'152 psi) in structural engineering.


It has the functions of rebound sampling, automatic recording, automatic storage, automatic calculation, strength result viewing, field bluetooth printing, background management settings, online upload data and so on. The work efficiency of rebound detection is greatly improved and the labor intensity of testing personnel is reduced.

main feature

Digital upgrade design

It adopts mobile phone keystroke technology and seven-key design. The product is characterized by better hand feeling, longer life, faster response, easier to operate.

The modular design of the electronic warehouse can be quickly assembled with the ordinary mechanical rebound apparatus into a new integrated digital rebound apparatus.

The rebound value is collected by non-contact grating and photocoupling sensor. There is no wire connection between the pointer block and the circuit board,Higher accuracy, more stable rebound value.

The computer online software adopts the latest data processing platform developed by LANGRY Technology, which has the function of automatic importing rebound value and automatic identifying port, integrating rich report formats and various data export formats, and giving users a more perfect experience.
