The SPI 17-609-9 is an electronic depth gage with a measurement range of 0 to 8 inches, designed for precision dimensional inspection in machining, fabrication, and quality-control environments. It delivers a resolution of 0.0005 inches and an accuracy of 0.0015 inches, making it suitable for close-tolerance work where analog depth gages fall short. The 4-inch stainless steel base provides stable contact across a workpiece surface, and the digital readout eliminates parallax error common with vernier-style instruments. SPC/USB data output allows direct integration with statistical process control software or a connected computer for logged measurement workflows.
This depth gage is used in precision machining shops, tool rooms, and quality-assurance departments for measuring slot depths, counterbore depths, step heights, and similar features. It is equally applicable in maintenance and manufacturing settings where repeatable, documented measurements are required. The IP54 water resistance rating provides protection against light coolant splash and dust, making it functional on or near active machine tools. Installation and use require no additional tooling beyond battery replacement when needed.
Designed as a standalone electronic depth measurement instrument compatible with standard depth gage applications requiring a 4-inch base and 0 to 8 inch range.
No installation is required for handheld use. If connecting via USB for SPC data output, ensure the appropriate driver or interface software is installed on the receiving device before use. Handle the stainless steel base and blade with care to avoid nicks or burrs that would affect measurement accuracy. Store in the provided case when not in use to protect the digital display and base surfaces.
