Operating across a range of 200 to 960 HL with a resolution of 1 HL and an accuracy of plus or minus 0.5 percent (Leeb), it delivers reliable readings without requiring a fixed bench setup. The unit uses a carbide ball indenter and runs on a rechargeable NiCd battery, making it well suited for service environments where AC power is not available. At 2 pounds, it is compact enough for one-hand operation during incoming inspection, weld verification, or in-service component assessment.\u003c\/p\u003e\n\u003cp\u003eThis tester is intended for use by quality control technicians, maintenance professionals, and metalworking trade shops performing non-destructive hardness verification. Typical applications include checking raw stock, verifying heat treat results, and assessing wear on in-service components. The Leeb scale is widely accepted for portable testing on larger workpieces that cannot be brought to a stationary Rockwell or Brinell tester. The package ships as a single unit with a minimum order quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeeb rebound scale with a measurement range of 200 to 960 HL\u003c\/li\u003e\n  \u003cli\u003eResolution of 1 HL for precise field readings\u003c\/li\u003e\n  \u003cli\u003eAccuracy of plus or minus 0.5 percent (Leeb)\u003c\/li\u003e\n  \u003cli\u003eCarbide ball indenter for durability across a variety of metal surfaces\u003c\/li\u003e\n  \u003cli\u003eNiCd rechargeable battery power source for cordless operation\u003c\/li\u003e\n  \u003cli\u003eLightweight at 2 pounds for comfortable single-hand use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a portable Leeb-method hardness tester suitable for use on ferrous and non-ferrous metals and alloys where component size or installation location prevents use of a stationary hardness tester.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo permanent installation is required. Ensure the test surface is clean, smooth, and free of scale or coatings that could affect rebound readings before use. Follow the manufacturer's calibration procedure using the supplied reference block prior to each testing session. Battery charging and storage should follow the NiCd care guidelines included with the unit to maintain long-term battery performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScale Type\u003c\/strong\u003e: Leeb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Range\u003c\/strong\u003e: 200 to 960 HL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Hardness\u003c\/strong\u003e: 200 HL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Hardness\u003c\/strong\u003e: 960 HL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 1 HL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.5% (Leeb)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndenter Type\u003c\/strong\u003e: Carbide Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Source\u003c\/strong\u003e: Battery\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery Type\u003c\/strong\u003e: NiCd\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.91 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21-619-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691217453362,"sku":"21-619-2","price":2285.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80c26a152ce58e8a31ef15fa03336c31.jpg?v=1788281639","url":"https:\/\/voomisupply.com\/products\/spi-21-619-2-portable-electronic-hardness-tester","provider":"Voomi Supply","version":"1.0","type":"link"}
