It delivers a resolution of 0.0005 inches and an accuracy of 0.0015 inches, making it suitable for detailed dimensional checks on parts, fittings, pipe ends, and mechanical components. The caliper features hardened stainless steel construction on both the body and jaws, with an IP54 rating that provides resistance to dust ingress and splash exposure. It is used by machinists, pipefitters, HVAC technicians, and field service professionals who require reliable, repeatable measurements during installation and quality checks.\u003c\/p\u003e\u003cp\u003eThe 29-004-9 is well suited for both inside and outside measurements, with a 2.4-inch jaw length that accommodates a wide range of workpieces. The included depth measurement rod extends its utility to slot and step measurements. An absolute encoder design eliminates the need to zero the caliper at power-up, allowing faster workflow on the job. The unit ships with a protective case and is powered by a CR2032 lithium battery. It fits applications in residential and commercial mechanical trades wherever caliper measurements are required during fabrication, service, or inspection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12-inch maximum measurement range with 0.0005-inch resolution\u003c\/li\u003e\n\u003cli\u003eAccuracy of 0.0015 inches for precise dimensional verification\u003c\/li\u003e\n\u003cli\u003eIP54 rated — resistant to dust and water splash\u003c\/li\u003e\n\u003cli\u003eAbsolute encoder eliminates zero-setting on power-up\u003c\/li\u003e\n\u003cli\u003eStainless steel body and jaws with hardened finish for durability\u003c\/li\u003e\n\u003cli\u003eIncludes inside diameter jaws, depth rod, and protective case\u003c\/li\u003e\n\u003cli\u003ePowered by CR2032 lithium battery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose electronic caliper suitable for dimensional measurement tasks across mechanical, HVAC, plumbing, and fabrication trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo installation is required for this measuring instrument. Before use, verify the jaws close fully to confirm zero reference or rely on the absolute encoder for immediate readings. Keep the measuring faces clean and free of debris to maintain accuracy.
