  • High Accuracy: ±1% FS with displacement resolution of 0.01 mm.
  • Peak Holding & Auto-Release: Captures peak values for 1–10 seconds, then resets for the next test.
  • GO/NG Tolerance Comparison: Indicator lights for instant pass/fail judgment.

Description

The SD-10~30B Series Digital Spring Tester is a versatile and highly accurate testing system designed for measuring spring extension, compression, push, and pull forces across a wide range of industries. With capacities ranging from 10 N up to 5000 N, the system accommodates various testing requirements through selectable test travel, platen sizes, and load resolutions depending on the model. Its compact bench-top design and intuitive control interface make it ideal for laboratory verification, incoming inspection, and production quality checks.

Equipped with advanced digital functions, the SD-10~30B improves repeatability and operator efficiency. It offers peak value capture with timed auto-release, GO/NG tolerance comparison with indicator lights, and memory averaging of multiple test results, ensuring precise and consistent outcomes. Additionally, RS-232C communication allows seamless data handling, and the adjustable auto power-off feature conserves energy while maintaining convenience for daily operations. The tester supports displacement resolution of 0.01 mm and interchangeable platen diameters of φ30, φ49, and φ108 mm, making it highly adaptable for various spring and force testing applications.
