Mitutoyo 7300A Dial Thickness Gage 0-0.5 in 0.001 Grad

Product Description

The MITUTOYO 7300A is a mechanical dial thickness gage designed to measure material thickness across a range of 0 to 0.5 inches with 0.001-inch graduation and 0.001-inch accuracy. The 2-inch dial face provides clear, easy readout in demanding shop or field conditions. The gage features a glare-free crystal and scratch-resistant coating, keeping the display legible through repeated use. Ceramic anvil faces resist wear and corrosion, making this instrument well-suited for environments where longevity and measurement integrity matter. A measuring force of 1.4 N ensures consistent contact pressure without distorting thin or compressible materials. Licensed HVAC technicians, plumbers, electricians, and sheet metal fabricators rely on this tool for verifying gasket, shim, and sheet stock dimensions.

The 7300A is used in residential and commercial trade applications wherever precise thickness verification is required. Its 1.1811-inch throat depth accommodates a variety of workpieces, including gaskets, sheet metal, rubber seals, insulation board, and thin-wall tubing. The flat anvil tip and 12 mm anvil face diameter provide stable contact on flat surfaces, while the 4 mm flat contact diameter on the upper spindle tip suits smaller measurement areas. This gage fits naturally into a technician tool kit for pre-installation material checks and quality verification tasks.

Compatibility

Designed as a general-purpose OEM-style dial thickness gage suited for trade and industrial applications requiring measurement of flat materials up to 0.5 inches thick with a flat contact anvil configuration.

Installation Notes

Precision measuring instruments should be handled and stored according to the manufacturer guidelines to maintain calibration. Before use, verify the gage zeroes correctly on a known reference surface. No electrical power or gas shutoff is required for operation. Periodic calibration by a qualified metrologist is recommended to ensure ongoing measurement accuracy, especially in high-use environments.
