Taijia HT-225 Concrete Rebound Hammer Rebound Tester Concrete Hardness Tester concrete test hammer

 detection of reinforcing steel measuring instrument is applied to test the compressive strength of building concrete components,bridge and so on.

   Standard: JGJ/T23-2011;GB /T9138-1988;JJG817-93 ; ASTM C 805

  1) Center rod is made from imported material, high accuracy and durable resistance

  2) The shell is made form high Aluminum or high polymer material in order to perfect

       protect instrument from damage and extend use life.

  3) Pointer slider is outside structure, its friction can be balance well and easy to be adjusted

      so that we can make sure that the instrument is accurate. Compared with other suppliers

     in the line of business, the product is more accuracy, good quality, and best price and longer use life

detection of reinforcing steel measuring instrument

1) Test anvil is the excellent instrument for assessing test hammer.

2) Test anvil is made from the best steel and especial tool steel. Contact area between anvil core and anvil body get excellently polished, and the rigidity of anvil core is HRC58~62

3) Test anvil must be located on horizontal ground, take test hammer operation on it and check the rebound value, qualified concrete test hammer will get a average rebound value of 80±2 on test anvil, qualified mortar test hammer will get a rebound value of 74±2.

4) The test anvil, as a calibration instrument, after each 5000 or 8000 test, the test surface can be polished and then continue using, but the rigidity of core must be HRC58~62, or abolish it.

5) Test anvil usually stored in dry dustproof place, protect its rebound surface from collision.

detection of reinforcing steel measuring instrument

ZBL-R630A is used to test the location of rebar in concrete, the thickness of the protective layer, and the diameter, orientationand distribution of rebar by using an electromagnetic induction method. It also can be used to test the distribution of magneticand conductor such as cables and metal pipes in non-magnetic medium and non-conducting medium

ZBL-R800 is a multi-functional integrated rebar detector which can be used for testing the thickness of protective layers, measuring the diameter, location, and distribution of rebar as well as for detecting the corrosion content of a rebar.

HT-225W+ digital test hammer with digital display and voice function, for the quick and easy determinationof the strength of concrete, and hardness of construction materials. Digital and voice functions allow fasterand greater number of test, leading to better quality tests.
