It covers a measurement range of 0 to 6 inches (0 to 150 mm) with a graduation of 0.001 inches (0.02 mm) and an accuracy of 0.03 mm. The caliper handles four measurement types in a single tool: outside, inside, depth, and step measurements. The beam and jaws are constructed from stainless steel with a satin chrome finish, providing corrosion resistance and long service life. A single set screw secures the sliding jaw during readings. The tool ships with a holster for storage and protection.\u003c\/p\u003e\u003cp\u003eThe 530-312 suits precision measurement tasks in HVAC, plumbing, electrical, and general mechanical trades where part dimensions must be verified before installation or fabrication. It is well suited for measuring pipe OD and ID, fitting dimensions, conduit sizing, and component clearances. The 1.5748-inch (40 mm) jaw depth allows access to recessed features and stepped surfaces. Inside diameter jaws and a depth measurement rod are included, making this a complete general-purpose measuring instrument for shop and field use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range: 0 to 6 inches (0 to 150 mm)\u003c\/li\u003e\n\u003cli\u003eGraduation of 0.001 inches (0.02 mm) for fine resolution readings\u003c\/li\u003e\n\u003cli\u003eAccuracy of 0.03 mm across the full range\u003c\/li\u003e\n\u003cli\u003eFour measurement modes: outside, inside, depth, and step\u003c\/li\u003e\n\u003cli\u003eStainless steel beam and jaws with satin chrome finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eIncludes inside diameter jaws, depth measurement rod, and protective holster\u003c\/li\u003e\n\u003cli\u003eSeries 530 sliding jaw design with single set screw lock\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose vernier caliper suitable for dimensional inspection and measurement tasks across mechanical, HVAC, plumbing, and electrical trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eVernier calipers require no installation but should be inspected for zero error before use by closing the jaws fully and confirming the vernier zero line aligns with the main scale zero. Keep the sliding surfaces clean and lightly oiled to maintain smooth jaw movement and measurement accuracy.
