Spi 31-176-1 Electronic Caliper 0-8 in Stainless Steel

Product Description

The SPI 31-176-1 is an electronic digital caliper designed for precise outside-dimension measurement in shop, field, and industrial environments. It covers a measurement range of 0 to 8 inches (0 to 200 mm) and delivers a resolution of 0.0005 inches with an accuracy of 0.0015 inches. The caliper body and jaws are both constructed from hardened stainless steel, providing resistance to wear and corrosion during regular use. Power comes from an LR44 battery. Machinists, pipefitters, HVAC technicians, and precision tradespeople rely on calipers like this for verifying outside diameters, fitting dimensions, and fabrication tolerances.

The SPI 31-176-1 is suited for outside measurement applications in residential and commercial trade environments, including HVAC fabrication, plumbing rough-in verification, and general mechanical work. Its 50 mm jaw length accommodates a wide range of workpiece geometries. Note that this model does not include inside-diameter jaws or a depth measurement rod, making it purpose-built for outside measurement tasks.

Key Features

• Measurement range: 0 to 8 inches (0 to 200 mm)
• Resolution of 0.0005 inches for fine-tolerance readings
• Accuracy rated at 0.0015 inches
• Hardened stainless steel body and jaws for durability and corrosion resistance
• Outside-jaw style with 50 mm jaw length
• Battery powered using a standard LR44 cell

Compatibility

Designed as a general-purpose outside-measurement electronic caliper suitable for trade and industrial measurement applications where a 0 to 8 inch range and 0.0005 inch resolution are required.

Installation Notes

No permanent installation is required for this instrument. Before use, ensure the jaws are fully closed and the display is zeroed. Keep the caliper clean and dry, and avoid exposing the electronic components to cutting fluids or excessive moisture. Replace the LR44 battery when the display dims or becomes erratic to maintain measurement accuracy.
