The SPI 17-615-6 is an electronic depth gage with a measuring range of 0 to 8 inches, designed for precision dimensional inspection in machining, manufacturing, and metalworking environments. It delivers a resolution of 0.0005 inches and an accuracy of 0.0015 inches, making it suitable for tight-tolerance work where analog gages fall short. The 4-inch base length provides stable seating across a wide range of bore and step measurements. Built from stainless steel with an IP54 water resistance rating, this gage holds up in shop environments where coolant and debris are present. It includes SPC and USB data output for integration with quality control systems.
This depth gage is used in machine shops, tool rooms, and quality inspection stations for measuring the depth of holes, slots, recesses, and steps on machined parts. The 4-inch base spans wider reference surfaces for more consistent readings. The included CR2032 battery and hook are ready for immediate use out of the box. It is appropriate for both production floor spot-checks and bench inspection work where digital readout and data logging are required.
Designed as a standalone electronic depth gage suitable for general-purpose dimensional inspection in machining and manufacturing applications where 0 to 8 inch depth measurement is required.
No installation is required for handheld depth gages. Before use, verify the base reference surface and the part surface are clean and free of burrs or debris that could affect accuracy. When connecting to a PC or SPC system via USB, use the appropriate interface cable and confirm data format compatibility with your data collection software. Battery replacement uses a standard CR2032 coin cell.
