Manufacturer of hand tool gages, force testing and metrology equipment, L.S. Starrett Co., has announced the introduction of a basic, spring testing solution designed for compression and extension springs. The new Starrett S1 Spring Testing Systems were developed for high volume production testing for users seeking more consistent results over manual testing methods.

Starrett S1 Systems feature test templates that enable the user to create a test set up quickly using one and two-point methods, with test targets being load or height-based. According to the company, the small footprint of the S1 System makes it well-suited for either lean manufacturing environments or in-situ production areas. The S1 System can measure spring rate, spring constant, free length, solid height and initial tension. Users can also set tolerances to determine immediate pass/fail results, which can be viewed in graphic or tabular formats.

“Our new Starrett S1 Spring Testers are a compact, easy to use, powerful, fast and cost-effective solution for basic production testing of springs,” said Emerson Leme, Head of Starrett Metrology Equipment Division.

Software features of Starrett S1 Spring Testing Systems enable the use of preconditioning options to exercise springs prior to testing, the ability to scrag for number of cycles or duration, or compress to a load set and hold for a duration. Single or dual test limits may be used and target load or height/length for determining spring rate, spring constant, load and length at target limits, initial tension and measured free length can be specified.

The system’s statistics view displays statistical information for the user’s batch including mean, range, standard deviations and tolerance results. Custom reports can also be printed out and data can be exported to Microsoft Excel or SPC Software such as ProLink’s QC CALC application.
