LS253 is a split-type Leeb hardness tester. The probe and the host are connected by aviation plugs, and the host is capable of automatically identifying the impact device. The instrument adopts advanced digital double-coil probe technology, which provides precise measurement results and great interference-resistance. Providing a variety of hardness scales , such as Leeb scale (HL), Vickers scale (HV), Brinell scale (HB), Shore scale (HS), Rockwell scale (HRA/HRB/HRC), and they can make a mutual conversion to avoid cumbersome manual calculation. Besides the hardness, the instrument can measure the strength of the materials. For various measuring needs, the instrument may be fitted with four different impact devices, D, DC, DL, and C.

Application

LS253 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.

Impact device selection

Features

Free to match 4 kinds of impact devices.

Aviation plugs link the host and impact device, and one host may be freely matched with up to four impact devices to meet various measuring settings.

Equipped with Bluetooth APP

The instrument is connected to the mobile phone APP through Bluetooth to realize multiple sets of data storage, and the measurement data can be shared.

Double coil technology, high precision, good repeatability

Using advanced dual-coil technology, it has good measurement accuracy and repeatability

Built-in direction sensor, all-round impact compensation

The probe contains an integrated direction sensor that accomplishes 360° all-around worry-free measurement by automatically compensating measurement mistakes in various direction

Conversions to different hardness scales

LS253 hardness tester provides a variety of hardness scales, which can be converted between Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS) and Rockwell (HRA/HRB/HRC) eliminating the cumbersome steps of manual table lookup.
