Using the UCI (Ultrasonic Contact Impedance) method, it delivers accurate hardness results directly on-site without the need for large samples or complex optical analysis.\u003c\/p\u003e\n\u003cp data-end=\"983\" data-start=\"600\"\u003eThe measurement principle is based on a vibrating rod with a Vickers indenter at its tip. When pressed against the sample at a defined test force, the resonance frequency of the rod changes as the indenter makes a microscopic impression. This frequency shift is converted into a hardness value, providing consistent results while leaving almost no visible mark on the test surface.\u003c\/p\u003e\n\u003cp data-end=\"1438\" data-start=\"985\"\u003eThis device is ideal for applications such as inspecting forgings, welds, castings, bearings, gear flanks, and heat-treated components. Compared to Rockwell and Brinell methods, it requires only a very small indentation, making the test nearly non-destructive. Unlike Vickers testing, there is no need for time-consuming optical evaluation. And compared to Leeb testing, the device works even on smaller or lighter samples, making it highly versatile.\u003c\/p\u003e\n\u003cp data-end=\"1727\" data-start=\"1440\"\u003eThe HO 5K complies with DIN 50159-1, ASTM-A1038-2005, and JB\/T9377-2013 standards. It includes advanced features such as storage for 1000 groups of readings, mini statistics for quick analysis, and calibration with up to 20 reference values for flexible use across different materials.\u003c\/p\u003e\n\u003ch4 data-end=\"1754\" data-start=\"1729\"\u003e\u003c\/h4\u003e\n\u003ch4 data-end=\"1754\" data-start=\"1729\"\u003e\u003cstrong\u003eTechnical Data\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul data-end=\"2187\" data-start=\"1755\"\u003e\n\u003cli data-end=\"1775\" data-start=\"1755\"\u003e\n\u003cp data-end=\"1775\" data-start=\"1757\"\u003eTest force: 50 N\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1798\" data-start=\"1776\"\u003e\n\u003cp data-end=\"1798\" data-start=\"1778\"\u003eDrive type: manual\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1850\" data-start=\"1799\"\u003e\n\u003cp data-end=\"1850\" data-start=\"1801\"\u003eHardness scales: HL, HV, HB, HRB, HRC, HRA, MPa\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1913\" data-start=\"1851\"\u003e\n\u003cp data-end=\"1913\" data-start=\"1853\"\u003eRockwell range: A 61–85.6 HRA, B 41–100 HRB, C 20.3–68 HRC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1942\" data-start=\"1914\"\u003e\n\u003cp data-end=\"1942\" data-start=\"1916\"\u003eBrinell range: 79–618 HB\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1977\" data-start=\"1943\"\u003e\n\u003cp data-end=\"1977\" data-start=\"1945\"\u003eTensile strength: 255–2180 MPa\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2012\" data-start=\"1978\"\u003e\n\u003cp data-end=\"2012\" data-start=\"1980\"\u003eMinimum sample thickness: 2 mm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2038\" data-start=\"2013\"\u003e\n\u003cp data-end=\"2038\" data-start=\"2015\"\u003eMinimum weight: 300 g\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2085\" data-start=\"2039\"\u003e\n\u003cp data-end=\"2085\" data-start=\"2041\"\u003eData memory: 1000 groups, 20 readings each\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2105\" data-start=\"2086\"\u003e\n\u003cp data-end=\"2105\" data-start=\"2088\"\u003eInterfaces: USB\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2157\" data-start=\"2106\"\u003e\n\u003cp data-end=\"2157\" data-start=\"2108\"\u003eMeasuring probe: 15.5 cm length, 18 mm diameter\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2187\" data-start=\"2158\"\u003e\n\u003cp data-end=\"2187\" data-start=\"2160\"\u003eHousing: metal, lacquered\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0946\/5105\/6463\/files\/SL_HO_5K_brochure.pdf?v=1758971415\"\u003eBrochure\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003ca href=\"https:\/\/zentra-eu.com\/pages\/downloads\" rel=\"noopener\" target=\"_blank\"\u003eCertifications\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width: 100%; max-width: 1000px; height: auto; display: block; margin: 0 auto;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0946\/5105\/6463\/files\/TD_HO_5K_data_page-0001.jpg?v=1758971378\"\u003e\u003cimg style=\"width: 100%; max-width: 1000px; height: auto; display: block; margin: 0 auto;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0946\/5105\/6463\/files\/TD_HO_5K_data_page-0002.jpg?v=1758971378\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e**All our products are brand new, shipped in the original packaging, and include manufacturer warranty**\u003c\/p\u003e","brand":"Kern \u0026 Sohn","offers":[{"title":"Default Title","offer_id":56022516891983,"sku":"HO-5K","price":4940.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/5105\/6463\/files\/HO-1K.jpg?v=1758969436","url":"https:\/\/zentra-eu.com\/en\/products\/kern-uci-hardness-tester-ho-5k","provider":"Zentra ","version":"1.0","type":"link"}
