Spi CMS170309008 Vernier Caliper 0-8 in Stainless Nist

Product Description

The SPI CMS170309008 is a stainless steel vernier caliper with a measurement range of 0 to 8 inches and a graduation of 0.001 inches, making it suited for precise dimensional inspection work in trade and industrial settings. Accuracy is rated at 0.0015 inches across the full range. Jaw depth measures 1.97 inches, providing reach for stepped and recessed features. The caliper ships calibrated with NIST traceability certification included, meeting documentation requirements for quality-controlled environments. A protective case is included. This tool is used by HVAC technicians, pipefitters, machinists, and maintenance professionals who need reliable linear measurement on components, fittings, and fabricated parts.

The CMS170309008 is appropriate for residential and commercial trade applications where part fitment, bore sizing, or component inspection requires sub-thousandth readability. The stainless steel construction resists corrosion in shop and field environments. It is commonly used during equipment installation, parts fabrication, and quality verification tasks where a calibrated, documented measurement tool is required by procedure or contract. The included NIST-traceable certificate supports use in calibrated-tool programs and service documentation workflows.

Compatibility

Designed as a general-purpose vernier caliper suitable for dimensional measurement tasks across HVAC, plumbing, electrical, and mechanical trade applications requiring a calibrated 0 to 8 inch stainless steel instrument.

Installation Notes

Vernier calipers require no installation but should be zeroed and inspected for jaw alignment before use. Store in the included case when not in use to protect the measuring faces and graduated beam. Avoid dropping or applying lateral force to the jaws, as this can affect accuracy. Recalibration should follow the interval specified by your quality program or applicable metrology standards.
