根据国家标准，纸张的抗张强度测试速度为12.5mm/min.该仪器除了能满足这个检测速度，同时可以在5-500mm/min的速度区间任意选择，该功能可以满足180°剥离、薄膜拉力等试样的检测。
According to the national standard, the test speed of paper tensile strength is 12.5mm/min. In addition to meeting the test speed, the instrument can also choose any speed range of 5-500mm / min. the function can meet the test of 180 ° peel, film tension and other samples.
该仪器不仅能检测拉力，也不止具备了纸张抗张强度的测试功能，同时还可以检测塑料薄膜、纸张的伸长率、拉断力、纸张的裂断长、抗张能量吸收、抗张指数、抗张能量吸收指数等等。
The instrument can not only detect the tensile force, but also has the testing function of paper tensile strength. At the same time, it can also detect the plastic film, paper elongation, breaking force, paper breaking length, tensile energy absorption, tensile index, tensile energy absorption index and so on.
