概述
新款德国Schmidt的ZEF和ZED系列张力计采用了应变计系统，能够精确测量跑线（运动中）的张力，测量材料范围有纱线，纤维，细线和细金属丝。其扳机操作滚轮换挡机制使得张力计轻松获取运动中材料张力测量。 自动调零功能使得操作中可以在任何测量方位下获得最高精度。 The new Schmidt 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 highest accuracy.
