TBT-HT05D concrete hammer 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.

TBT-TH05DS concrete test hammer achieves digital reporting and data sharing via USB interface and Bluetooth. This test hammer is available in wirelessly connecting to a Bluetooth printer and directly printing out test results.
Digital part can be separated from main body and coupled with mechanical hammer by a simple push. Once the hammer broke during testing, can easily exchange another hammer and continue to work. The hammer can work as normal without digital part as well. By Bluetooth data in memory can be downloaded to PC or micro printer wireless.

- Test anvil is an excellent instrument for assessing test hammer.
- Test anvil is made from high quality steel and special tool steel. The contact area between anvil core and anvil body has been well polished, and the rigidity of anvil core is HRC58~62.
- Test anvil must be located on horizontal ground for taking test hammer operation on it and checking the rebound value. The qualified concrete test hammer will get an average rebound value of 80±2 on test anvil, when the qualified mortar test hammer will get a rebound value of 74±2.
- The test anvil, as a calibration instrument, after each 5000 or 8000 test, the test surface can be polished for long-lasting use. The rigidity of core must be HRC58~62, or we will abolish it.
- Test anvil is usually stored in dry dustproof place that protects its rebound surface from collision.
