Check the tension on wire or filaments right where they’re used to keep spooling, EDM wire cutting, and 3D printing systems running smoothly. These gauges test fixed or moving materials, which lets you take tension readings while equipment is stopped or running for continuous monitoring. They can also be used on thin wire rope, carbon fiber, and fiber-optic strands. Slide your material between their contact-point rollers to take measurements, even in tight spaces. All include a calibration certificate traceable to NIST that states they've passed a test to confirm accuracy.
