Master Calibrated Springs
Verify Spring Tester Calibration

Master Calibrated Springs are used to periodically verify a spring tester is within its calibration parameters.

  • Verification compliance for ISO-9000
  • 10 / 35 / 100 / 200 / 250 / 400 / 500 / 550 / 750 / 1,000 lbf capacities
  • Reliable and convenient force standard
Master Calibrated Springs are used to periodically verify a spring tester is within its calibration parameters. In five minutes or less, Master Calibrated Springs can provide confidence and compliance with your ISO-9000 equipment verification procedures. A Spring Calibration Certificate is provided with every Master Calibrated Spring.

What are Master Calibrated Springs?
LSI’s Master Calibrated Springs are specifically designed with characteristics that make them a very reliable and convenient force standard, such as: low mechanical stress levels, multiple coils, exacting end squareness, multiple presetting to eliminate set and low rate. Spring calibration includes multiple tests and is NIST traceable.

Intended Uses of Master Calibrated Springs
The master calibrated spring is intended to verify force calibration of spring testers. With a five-minute procedure, Master Calibrated Springs can provide confidence and compliance with your ISO-9000 equipment verification procedures. The Master Calibrated Spring is not intended to calibrate spring testing equipment, since calibration requires a more exact standard. The Master Calibrated Spring can also be used in a variety of applications in which a known force must be applied.
