Spi 17-994-5 Dial Caliper 200mm Nist Certified Stainless Steel

Product Description

The SPI 17-994-5 is a stainless steel dial caliper designed for precise linear measurement in professional metrology, machining, and quality-control applications. It covers a full 200 mm measurement range with a dial graduation of 0.01 mm and 1 mm per revolution of the dial indicator, delivering an accuracy of 0.03 mm. The caliper measures outside, inside, depth, and step dimensions from a single tool. It ships NIST-traceable certified and calibrated right out of the box, making it ready for immediate use in inspection and manufacturing environments.

This caliper is suited for machine shops, fabrication facilities, toolrooms, and quality-assurance departments where metric precision measurement is required. The 50 mm jaw length accommodates a wide range of workpiece geometries for both inside and outside measurements. It is appropriate for use by machinists, metrology technicians, quality inspectors, and trade professionals who require a reliable, certified dial caliper for daily production or inspection tasks. The included fitted case protects the instrument during storage and transport.

Key Features

• 200 mm measurement range with 0.01 mm dial graduation and 1 mm per revolution readout
• Measures outside, inside, depth, and step dimensions

Compatibility

Designed as a general-purpose metric dial caliper suitable for standard linear measurement tasks in machining, fabrication, and quality-control environments where a 200 mm range and 0.01 mm graduation are required.

Installation Notes

Dial calipers require no installation but should be zeroed before use by closing the jaws fully and confirming the dial reads zero. Keep the measuring surfaces clean and free of chips or debris before taking measurements. Store the caliper in the included fitted case when not in use to prevent damage to the jaws and dial mechanism. Calibration should be verified periodically against a traceable standard in accordance with your facility quality program.
