Introduction LS252DC is an advanced lipstick-sized metal hardness tester which incorporates the impact device and controller into one unit. It easily fits in a pocket or your palm. 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 OLED display screen. Equipped with impact device DC, the Leeb hardness tester is suitable for very confined spaces such as holes, cylinders or for internal measurements on assembled machines. The battery can be charged simply from USB port, also it has a customer re-calibration function. Application LS252DC 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 is suitable for very confined spaces such as holes, cylinders or for internal measurements on assembled machines.
