Brief introduction: This instrument is specially used in testing the compressive strength of mortar in building brick component. Trait: 1）Center rod use imported materials, high precision, wear proof. 2）Shell made from super hard aluminum, perfectly protect instrument from damage on site work, and prolong use life.； 3）Pointer slider is outside ring structure, easy to adjust friction, and assure the equal friction between pointer slider and axis, so that assure the accuracy of instrument. Compare with other brand similar product, it’s better accuracy, longer use life. Parameter: Test range: 1.0~25Mpa Standard impact energy: 0.196J(0.02kgf.m) Stroke of rebound hammer: 75mm Friction of pointer slider: 0.4N~0.6N Sphere radius of rebound pole SR: 25mm Average rebound hammer on steel anvil: 74±2 Size: Φ54*268mm Weight: ≈1KG |
