ZC3-A concrete test hammer 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

How to work with ZC3- A Concrete rebound hammer | ||
1 | Use a grinding stone to smoothen the test surface | |
2 | Perform a few test impacts with the rebound hammer on this smooth, hard surface before taking any measurements which you are going to evaluate. Perform a consistency check on the test anvil | |
3 | Position the hammer perpendicular to and against the test surface. Push the concrete test hammer adainst the surface at a moderate spped until the impact is triggered. Bes aware that the plunger generates a recoil when it deploys. |
