Spi CMS160714020 Dial Drop Indicator 0.25 in Range

Product Description

The SPI CMS160714020 is a dial drop indicator designed for high-precision linear measurement in machining, inspection, and metrology applications. With a measurement range of 0.25 inches and a dial graduation of 0.0005 inches, this indicator delivers fine resolution suitable for surface runout checks, flatness inspection, and part alignment verification. The 0-25-0 bidirectional dial reading allows technicians to detect deviation in either direction from zero without resetting. A NIST Traceability Certification is included, making it suitable for environments that require documented measurement standards. Measuring force is 1.50 newtons, helping minimize deflection on sensitive workpieces.

This dial drop indicator is used in machine shops, tool rooms, and quality control stations where small linear displacements must be measured accurately. It is appropriate for use on surface plates, magnetic bases, and articulating arm fixtures in both production and inspection settings. The flat back style and 3/8-inch stem diameter are compatible with standard indicator holders and accessories. The 0.05 inches range per revolution keeps the scale readable during fine positioning work. Installation and use are typically performed by machinists, metrologists, or precision measurement technicians.

Key Features

• 0.25 inch total measurement range with 0.0005 inch graduation for fine-resolution readings
• 0-25-0 bidirectional dial reading for deviation measurement in both directions
• 1.61 inch white dial face for clear, high-contrast readability
• NIST Traceability Certification included to support quality system documentation
• Flat back style with 3/8-inch stem diameter for compatibility with standard indicator holders
• Counter pointer and universal positioning capability for flexible setup

Compatibility

Designed for use with standard dial indicator holders, magnetic bases, and articulating arm fixtures that accept a 3/8-inch stem diameter. Meets US Federal Specifications and NIST Certified standards as stated by the manufacturer.

Installation Notes

Dial drop indicators are installed and used by machinists and inspection technicians. Secure the 3/8-inch stem firmly in the holder to prevent movement during measurement. Zero the indicator dial before taking readings and verify contact point seating on the workpiece. Do not exceed the stated measurement range, as overtravel can damage the indicator mechanism.
