新款Checkline的ZEF和ZED系列張力計采用了應變計系統，能夠精確測量跑線（運動中）的張力，測量材料范圍有紗線，纖維，細線和細金屬絲。其扳機操作滾輪換擋機制使得張力計輕松獲取運動中材料張力測量。
自動調零功能使得操作中可以在任何測量方位下獲得精度。
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 highest accuracy.
