Replaced by new ZEF and ZED models
4 capacities, 50, 100, 200 and 500 grams / cN
The new CHECKLINE 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.
Automatic zero permits operation in any orientation while maintaining the highest accuracy.
