ZEF - ZED电子张力计

ZEF - ZED Economical, Limited Access Digital Tension Meter

The new CHECK-LINE models 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.
