The hardened and ground base provides a flat reference surface, and the graduated main vial allows quantitative measurement of inclination rather than simple level indication. The cylindrical barrel vial assembly is removable and reversible for error-checking via the reversal method. This example is used in good condition; the cast iron base shows typical use wear and the paint has minor scuffing consistent with shop use, but the vials are intact and the ground base appears serviceable.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct Specifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;\"\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eStarrett\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eModel Number\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e98-18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eBase Length\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e18 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eNumber of Vials\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eMain Vial Type\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eGround and graduated, cylindrical barrel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eCross-Test Vial\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eYes, recessed in body\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eBase Material\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eCast iron\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eBase Surface\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eGround\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eVial Sensitivity (main)\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e0.005 in\/ft per graduation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eUsed — good\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"DDT and More","offers":[{"title":"Default Title","offer_id":48796597059799,"sku":"1804t68D","price":183.35,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/0626\/7095\/files\/starrett-no-98-18-1.jpg?v=1781806743","url":"https:\/\/dansdiscounttools.com\/products\/starrett-98-18-18in-machinist-level-4-vials-ground-graduated-1","provider":"Dan's Discount Tools","version":"1.0","type":"link"}
