It measures up to 8.0 inches (203 millimeters) with a resolution of 0.016 inches and an accuracy of 0.001 inches. The caliper body and jaws are constructed from stainless steel, providing corrosion resistance and long-term durability in shop and field environments. Jaw adjustment is handled via a thumb wheel for controlled, repeatable positioning. The unit ships with a silver oxide SR44 battery installed and a protective case. Licensed tradespeople, machinists, pipefitters, and HVAC technicians use this tool when tight dimensional tolerances are required.\u003c\/p\u003e\n\u003cp\u003eThe GENERAL 1478 is suited for residential and commercial trade work wherever accurate inside diameter, outside diameter, depth, and step measurements are needed. The knife-edge jaw style allows access to narrow grooves and recessed features that standard flat jaws cannot reach. A dedicated depth rod extends from the base of the caliper for direct depth measurement without a separate tool. The included inside diameter jaws handle bore and ID measurements in a single instrument, reducing the number of tools needed on the job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasures up to 8.0 inches (203 millimeters) maximum range\u003c\/li\u003e\n  \u003cli\u003e0.016 inch resolution with 0.001 inch accuracy\u003c\/li\u003e\n  \u003cli\u003eStainless steel body and jaws for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eKnife-edge jaw style for access to narrow slots and recessed features\u003c\/li\u003e\n  \u003cli\u003eIntegrated depth rod for depth measurements without a secondary tool\u003c\/li\u003e\n  \u003cli\u003eIncludes inside diameter jaws, SR44 silver oxide battery, and protective case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose electronic caliper suitable for HVAC, plumbing, pipefitting, machining, and related trade measurement applications requiring inside diameter, outside diameter, depth, and step readings up to 8.0 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required. Before use, verify the caliper zeroes correctly with jaws fully closed. Replace the SR44 silver oxide battery when the display dims or readings become inconsistent.
