LS252D is an advanced state-of-the-art palm sized metal hardness tester which incorporates the impact device and controller into one unit. It easily fits in a pocket. It used lastest dual-coil technology which makes the tester to have extraordinary accuracy: ±6 HL and good repeatability:6HL. It adopts orientation sensors that will compensate the measurement errors in different impact directions automatically to ensure the accurate data, with durable metal housing and OLED display screen. Equipped with impact device D, LS252D is especially suitable for almost any object, polished parts and heat-treated surfaces or the situation requiring a large number of tests. The battery can be charged simply from USB port, also it has a customer re-calibration function.
Application
LS252D handy Leeb hardness tester is suitable for testing the hardness of materials such as steel, cast steel, alloy steel, stainless steel, gray cast iron, ductile iron, cast aluminum alloy, copper-zinc alloy, copper-tin alloy, pure copper and forged steel. The instrument can be widely used in machine tool guides, automotive chassis, heavy workpieces, mold cavities, bearings, pressure vessels and installed machinery or assembly parts and can help manufacturers to carry out product quality inspection and reasonable process analysis.
