Tensile Strength Tester for Paper and Paperboard

Product Description:

The fully automatic horizontal computerized tensile tester is a specialized instrument designed to measure parameters such as paper tensile strength and wet tensile strength. Featuring a horizontal design, the instrument is compact, fully functional, and easy to operate. It employs a pneumatic clamping mechanism that ensures the specimen remains flat, thereby reducing human error associated with manual clamping devices; this design represents a first-of-its-kind innovation in the domestic market. Utilizing state-of-the-art ARM technology, the instrument offers powerful data processing capabilities, automatic reset functionality, easy adjustment, and stable performance. It features a large-screen color touchscreen LCD display with a Chinese menu, providing real-time display of all data and tensile curves.

Product Features:

Measures paper tensile strength, tensile energy absorption, elongation, tear length, tensile energy absorption index, and tensile index
Measures the wet tensile strength of tissue paper (available in manual or fully automatic modes)
