This product has been replaced by the ZEF Tension Meter
Economical Digital Tension Meter
3 Ranges up to 500g
For a wide variety of yarns, fibers and fine wires
Replaced by new ZEF Limited Access Digital Tension Meter and ZED Digital Tension Meter models
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
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
| 
ZED Models - This model is recommended for all other applications where miniaturized rollers are not necessary
