Economical Digital Tension Meter

3 Ranges up to 500g

For a wide variety of yarns, fibers and fine wires

The ZEF and ZED Tension Meters employ a strain-gauge system for accurately measuring the running line tensions on a wide variety of yarns, fibers and fine wires. Its trigger-operated roller shifting mechanism makes it easy to acquire the running material.

Single-button automatic zero permits operation in any orientation while maintaining highest accuracy

Applications
line

ZEF Models

Miniature rollers make these models ideal for delicate yarns/fibers and fine wires as well as those application where access space is limited
For Spandex and similar materials, specify model ZEF-100-T

line

ZED Models

This model is recommended for all other applications where miniaturized rollers are not necessary
