It measures from 0 to 0.25 inches with a resolution of 0.0001 inches and an accuracy of 0.0001 inches, making it suitable for applications that demand tight tolerances. The lug back mounting style allows secure attachment to magnetic bases and indicator holders. A 3-volt battery powers the electronic display, providing clear digital readout without the parallax error common to analog dial indicators. This instrument is typically used by machinists, toolmakers, and metrology technicians.\u003c\/p\u003e\u003cp\u003eThe VRS2500-0-03 is suited for surface plate inspection, fixture alignment, runout measurement, and flatness verification. Its 0.38-inch stem diameter is compatible with standard indicator holders and collet-style clamps found on most surface gauge arms and magnetic base assemblies. The compact form factor and lug back design make it a practical choice for tight setups where space is limited. It fits into general-purpose inspection workflows in both production and tool room settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range of 0 to 0.25 inches (0 to 6.35 mm) for short-stroke precision work\u003c\/li\u003e\n\u003cli\u003eResolution and accuracy of 0.0001 inches (0.002 mm) for tight-tolerance inspection\u003c\/li\u003e\n\u003cli\u003eLug back mounting for compatibility with standard indicator holders and magnetic bases\u003c\/li\u003e\n\u003cli\u003e0.38-inch stem diameter fits standard collet clamps and indicator arms\u003c\/li\u003e\n\u003cli\u003eDigital electronic display eliminates parallax reading error\u003c\/li\u003e\n\u003cli\u003ePowered by a common 3-volt battery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard indicator holders, magnetic base assemblies, and surface gauge arms that accept a 0.38-inch stem diameter.
