CST - Coil Spring Tester
Coil Spring Tester

The Coil Spring Tester is a low cost alternative for high capacity springs. Test up to 1,500 lbs and get good force / length results from this sturdy two-post frame. The CST uses LCD readouts for easy viewing of highly accurate length and force measurements. The length measurement units can be selected to read in inches or millimeters while force measurement is selectable to read in pounds, kilograms, or Newtons. The CST measures flexible items in compression only. Although low in cost, the CST features a high degree of built-in precision and accuracy to assure excellent repeatability and reproducibility.

All of the Larson manual testers have deflection compensation for load cell and frame deflection. Because the testers have compensation with integrated force and length measurements, the length reads accurately at any force. This eliminates the need to use lookup tables to correct for the displayed length error. The Larson length reading is accurate as displayed.

The Coil Spring Tester is made with a rugged two-post steel frame and instrumented with a Larson precision load cell for force, a glass scale for length and our proprietary precision electronics for analysis and display of exact measurements.
