10Mpa to 70Mpa Concrete Test Hammer
Features:●Center rod is made from imported material, high accuracy and durable resistance. ●The shell is made form high Aluminum or high polymer material in order to perfect protect instrument from damage and extend use life. ●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.  |
The HT225 Concrete Test Hammer is designed specifically for the non-destructive testing of concrete structures. This method has considerable advantages over conventional methods of assessing the compressive strength of concrete in that large areas can be tested in a very short time at a very low cost.
In addition it is possible to determine the variation in concrete quality between different sections of a structure with case.
The HT225 is comparable with the Schmidt Hammer, Type N, this method of testing is covered by DIN 1048 and BS1881 part 202. These standards refer to assessment of the rebound hardness of motar which is directly related to the compressive strengths of the material being tested.
