乾熱收縮試驗機儀用於在加熱條件下測試材料收縮率以及收縮力的雙頻道儀器。包含工業紗線、實驗紗線、塑膠絲、磁帶、細絲、單纖維絲、混合絲、短纖紗等以及紡織品應用到的尼龍、聚乙烯、聚酯、聚丙烯和纖維膠等。

SmartForce 收縮測試儀能檢測紗線樣品在特定溫度（溫度可達250℃）的自由熱收縮率或者收縮力。 一次可以同時測量兩根樣品或者任選一根，可以同時測量收縮率或者收縮力或一個收縮率一個收縮力測試，測試溫度與時間可調。溫度精度同三型和五型一樣完美。

SmartForce 包含一個加熱裝置和電腦軟體包。加熱裝置包含加熱器、溫控表、收縮率和收縮力測量傳感器和一個數據裝置。

Testrite最初的收縮測試設備符合ASTM D4974標準，現在也符合EN 13844。本新型設備和原有型號相容。

提供的軟體包採用使用者友善界面，工作於Windows 2000，XP，Vista系統等，所有測試參數可通過電腦設定，並對結果進行多樣性組合。

Testrite從1965年開始生產紗線自由收縮實驗測試設備，在此領域擁有相當豐富的經驗。設備最初設計應用於鄧祿普，測試他們的輪胎簾線。很多著名簾線紡紗製造商使用Testrite作為他們的標準。

Testrite SmartForce Shrinkage Tester

The Testrite SmartForce™ Shrinkage Tester is a sophisticated dual-channel shrinkage and force measurement instrument designed to test the performance of materials under heat stress including industrial and technical yarns, plastic, tapes, filament, monofilament, hybrid and spun yarns for textile applications such as nylon, polyethylene, polyester, polypropylene and viscose, etc.

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.The duration of test is also variable. As with the Mk3 and Mk5 models the temperature is closely and accurately controlled.

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.

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)

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.

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 can also supply a suitable PC if required.
