MH320 Portable Hardness Tester is a kind of high-tech grade portable hardness testing instrument, which is widely used in various metal material;equips with built-in mini-printer, it can easily print out testing result on-site; moreover, Large LCD digital screen with 128×64 dot matrix enables it to display not only figure, but also character. Customers who are in need of directly printing data out on-site, and enjoying a digital as well as high-tech testing feel, this is the best choice.



Main Application:

Die cavity of molds
Bearings and other parts
Failure analysis of pressure vessel, steam generator and other equipment
Heavy work piece
The installed machinery and permanently assembled parts
Testing surface of a small hollow space
Material identification in the warehouse of metallic materials
Rapid testing in large range and multi-measuring areas for large-scale work piece
►128×64 dot matrix LCD Large Digital screen, displaying all functions and parameters;

►6 Exchangeable hardness scales: HRB, HRC, HV, HB, HS, HL, 3 types of strength values, Suitable to measure the hardness of all metallic materials;

►7 impact devices available for special usage, automatically identify the type of impact devices;

►500 groups storage capacity,including single measured value, average value, testing data, impact direction, impact times, material and hardness scale etc;

►Built-in mini-printer, enable to print testing result on-site;

►Equips with USB port, standard along with multi-functions data proceeding software, enable to connect to PC and make further data analysis;

►Suitable to preset upper and lower limit can be preset,alarm automatically when the result value exceeding the limit;

►Humanized user calibration function;
