Product Description
Product Description machinery schmidt 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 lifemachinery schmidt hammerTechnical parametersStandard impact energy2.207±0.1J (0.225Kgf.m)The static friction of pointer slider0.65N±0.15NLength of spring stretch75±0.3mmAverage rebound hammer on steel anvil Rm80±2Measuring Range10~60MpaRadius of spherical tip25mm±1mmWorking Temperature-10℃~+50℃Working Humidity≤90%RHDimensionsΦ54x280mmNet weightAbout 1.0KgDetailed ImagesHow to workHow to work with machinery schmidt hammer1Use a grinding stone to smoothen the test surface2Perform 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 anvil3Position 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. CalibrationTesting Anvil For machinery schmidt hammer1) 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 HRC58~623) 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.Related ProductsZBL-R630A Rebar scanner 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 mediumZBL-R800 Multifuncational Rebar detector 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.TEM912 integrity voice report digital concrete rebound hammerTEM912 Series DIGITAL TEST HAMMER automatically Record, Save,Calculate and Processing data.Contact UsTrade terms1. 18 Month's Warranty.2.
