The SmartForce™ Shrinkage Tester can determine the free Thermal Shrinkage or Shrinkage Force in a yarn as it is exposed to a pre-set temperature ranging from ambient to 250°C （max）. One or two samples can be tested simultaneously and with a choice of either two free shrinkage, two force or one of each at the same time.Theduration of test is also variable. As with the Mk3 and Mk5 models the temperature is closely and accuray controlled.

SmartForce 收缩测试仪能检测纱线样品在特定温度（室温至250℃）的自由热收缩率或者收缩力。 一次可以同时测量两根样品或者任选一根，可以同时测量收缩率或者收缩力或一个收缩率一个收缩力测试，测试时间可调。温度精度同三型和五型一样*。

The SmartForce™ System consists of an oven unit and a PC software package. The oven unit comprises the heater, temperature controller, shrinkage and force measuring transducers and a data unit, all housed in a robust steel cabinet.

SmartForce 包含一个加热单元和电脑软件包。加热单元包含加热器、温控表、收缩率和收缩力测量传感器和一个数据单元。

The original Testrite Shrinkage Tester was used for the development of the ASTM D4974 designated test method and also conforms to EN 13844. Now this new updated model also conforms as does its predecessors, the Mk3 and Mk5 （which are still available）

Testritezui初的收缩测试设备符合ASTM D4974标准，现在也符合EN 13844.本新型设备和原有型号兼容。

The software package supplied is very user friendly and works on Windows 2000, XP or Vista. All the test parameters are set using the computer and allow a variety of result combinations.提供的软件包采用用户友好界面，工作于Windows 2000，XP，Vista系统等，所有测试参数可通过电脑设定，并对结果进行多样性组合。

Testrite has produced yarn free shrinkage testing measurement machines since 1965 and boast a wealth of experience in this field. The first unit was originally designed for Dunlop to test their tyre cord yarns. Many famous tyre cord manufacturers use Testrite as their standard.

Testrite从1965年开始生产纱线自由收缩实验测试设备，在此领域拥有相当丰富的经验。设备zui初设计应用于邓禄普，测试他们的轮胎帘线。很多*帘线纺纱制造商使用Testrite作为他们的标准。

电脑可选配。
