ZED Digital Economical tension meter for limited access
Economical low tension measuring instrument for checking fibers, yarns and fine wires in areas with limited access. The ZED employs a strain-gauge system to measure the running line tension on a variety of yarns, fibers and fine wires accurately.
The running material can easily be acquired by the trigger-operated roller shifting mechanism. The single-button automatic zero permits operation in any orientation and guarantees simple operation and highest accuracy.
