Beijing TimesTIME5104 (formerly TH174) Leeb Hardness Tester is a small Leeb Hardness Tester, which is convenient for hardness measurement in a small area.It is suitable for testing the hardness of metal materials.TIME5104 Leeb Hardness Tester is a digital display type, which adopts an integrated structure with a built-in impact device, and adopts a full-Chinese operation language, which is smooth, simple and convenient to operate.TIME5104 Leeb Hardness Tester comes with a USB interface and can also be connected to a printer.
Beijing Times TIME5104 Leeb Hardness Tester adopts DL type impact device, TIME5104 the indication error of the Leeb Hardness Tester is ±12HLDL, and the repeatability of the indication value is ±12HLDL. Due to the different types of impact devices, the products of the same series of Leeb Hardness Testers will lead to different indication errors and repeatability. But the other basic information parameters are the same.
Leeb Hardness Tester is a new type of pocket-sized integrated hardness testing instrument, which is mainly suitable for testing the hardness of metal materials. Easy to carry, wide measurement range of characteristics, it is based on the Leeb hardness principle, measured Leeb (HL) hardness value through the program automatically converted into Brinell, Rockwell, Vickers, Shore and other hardness values, can also be configured with a variety of test accessories, to meet a variety of test conditions and environment, mainly suitable for rapid hardness testing of metal materials, especially suitable for large parts and non-detachable parts of the field hardness test.
