Using the ultrasonic contact impedance (UCI) method, it provides accurate hardness measurements with minimal damage to the test surface. This makes it ideal for on-site inspections, production checks, and quality assurance tasks.\u003c\/p\u003e\n\u003cp data-end=\"1158\" data-start=\"698\"\u003eThe principle is simple yet effective. The device uses a vibrating rod that operates at ultrasonic frequency and presses a Vickers indenter onto the sample with a defined test force. The resonance frequency shifts as soon as the indenter creates a small impression in the material. This change is then converted into a hardness value. The indentation is microscopic, meaning the test is almost non-destructive, unlike traditional Rockwell or Brinell testing.\u003c\/p\u003e\n\u003cp data-end=\"1596\" data-start=\"1160\"\u003eThe HO 2K is particularly useful for small forgings, weld seams, castings, tool steels, bearings, and gear flanks. It can also be used for testing the effects of heat treatment. Compared with optical Vickers testing, the HO 2K requires no complex microscopes, allowing quick measurements directly on installed parts. Compared with Leeb hardness testing, it does not require heavy samples, which makes it highly versatile in the field.\u003c\/p\u003e\n\u003cp data-end=\"1942\" data-start=\"1598\"\u003eIt supports multiple hardness scales including Rockwell, Brinell, Vickers, and even tensile strength values. Up to 1000 groups with 20 readings each can be stored, and results are supported by mini statistics such as max, min, and average. Calibration is simple with up to 20 reference values available, ensuring flexibility across materials.\u003c\/p\u003e\n\u003ch4 data-end=\"1969\" data-start=\"1944\"\u003e\u003cbr\u003e\u003c\/h4\u003e\n\u003ch4 data-end=\"1969\" data-start=\"1944\"\u003e\u003cstrong\u003eTechnical Data\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul data-end=\"2313\" data-start=\"1970\"\u003e\n\u003cli data-end=\"1990\" data-start=\"1970\"\u003e\n\u003cp data-end=\"1990\" data-start=\"1972\"\u003eTest force: 20 N\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2042\" data-start=\"1991\"\u003e\n\u003cp data-end=\"2042\" data-start=\"1993\"\u003eHardness scales: HL, HV, HB, HRB, HRC, HRA, MPa\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2116\" data-start=\"2043\"\u003e\n\u003cp data-end=\"2116\" data-start=\"2045\"\u003eMeasuring ranges: Rockwell 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=\"2145\" data-start=\"2117\"\u003e\n\u003cp data-end=\"2145\" data-start=\"2119\"\u003eBrinell range: 79–618 HB\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2180\" data-start=\"2146\"\u003e\n\u003cp data-end=\"2180\" data-start=\"2148\"\u003eTensile strength: 255–2180 MPa\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2215\" data-start=\"2181\"\u003e\n\u003cp data-end=\"2215\" data-start=\"2183\"\u003eMinimum sample thickness: 2 mm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2241\" data-start=\"2216\"\u003e\n\u003cp data-end=\"2241\" data-start=\"2218\"\u003eMinimum weight: 300 g\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2293\" data-start=\"2242\"\u003e\n\u003cp data-end=\"2293\" data-start=\"2244\"\u003eData storage: 1000 groups with 20 readings each\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"2313\" data-start=\"2294\"\u003e\n\u003cp data-end=\"2313\" data-start=\"2296\"\u003eInterfaces: USB\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_2K_brochure.pdf?v=1758970679\"\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_2K_data_page-0001.jpg?v=1758970654\"\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_2K_data_page-0002.jpg?v=1758970655\"\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":56022461186383,"sku":"HO-2K","price":5977.4,"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-2k","provider":"Zentra ","version":"1.0","type":"link"}
