JH180 Portable Leeb hardness tester is the company's first R & D Molded an economical portable hardness tester. Leeb hardness measuring instrument based on the principle, you can quickly and easily measure a variety of metal materials, instantly display the hardness measurements, while the system's available in a variety of hardness (Brinell HB, Rockwell HRC, Vickers HV, Shore HS) conversion between freedom, tolerance limits can be set in advance, out of range alarm. The product is available with a host of data processing software, convenient and PC for data conversion and parameter settings, support site dedicated printer connected to the print function. Low-power integrated circuit design relies on stable IC, AA No. ordinary batteries about 200 hours of standby and portable for field operations. Chinese display, menu operation is simple and convenient, seven kinds of special-shaped impact device requires no calibration, automatic identification. ? Application materials: steel and cast steel, alloy tool steel, stainless steel, gray iron, ductile iron, cast aluminum, copper and zinc alloy (brass), copper-tin alloy (bronze), copper, forged steel, roll, special materials can be customized conversion table. Product Features: ?? based Leeb hardness measuring principle, can detect a variety of metal materials for high precision. ?? Support "forged steel (Steel)" material, when using D / DC type impact test "forged" sample, it can directly read the HB value, without manual look-up table. ?? Facilitate the switch to all standard hardness (HL, HB, HRB, HRC, HRA, HV, HS), a parallel system to convert the measured hardness value each.
