Product Introduction 
The Intelligent Automatic tensile strength tester uses a horizontal constant-rate-of-elongation principle. A servo motor drives a precision ball screw to apply a constant tensile load to a standard-sized specimen until it ruptures. A high-precision load cell and data acquisition system record real-time force and deformation. The instrument features a microcomputer control system and a large color touchscreen, allowing flexible setting of test speed, specimen dimensions, and other parameters. The unique pneumatic clamping system, with adjustable pressure and speed, securely holds even delicate specimens like tissue paper without damage. After testing, the software automatically calculates and displays all tensile parameters and supports data storage and report printing.

Key Features 
Pneumatic Clamping, A Domestic Innovation Uses a pneumatic clamping structure with adjustable pressure and speed, ensuring flat and damage-free specimen gripping, completely eliminating manual clamping errors, especially for fragile samples.
High-Precision Servo Drive System Imported servo motor offers digitally adjustable testing and return speeds from 1 to 420 mm/min, ensuring precise control and low noise.
0.001N Ultra-High Resolution Measuring range of 0-30 N with an accuracy of 0.01 N and a resolution of 0.001 N, accurately capturing minute force variations for low-grammage paper testing.
Fully Automatic Multi-Parameter Testing One-touch operation completes the test and automatically calculates all parameters, including tensile strength, elongation, breaking length, TEA, and their indices.
Color Touchscreen and Real-Time Curves Large color touchscreen LCD with a multi-language menu and real-time force-deformation curve display for an intuitive testing process.
Powerful Data Statistics and Reporting Automatically calculates and prints a full test report with average, standard deviation, and coefficient of variation, with data memory functionality.
Variable Specimen Size for Flexibility Specimen length can be set between 30 and 180 mm to accommodate various standard or non-standard testing requirements.
Safe and Reliable with Auto-Return Features overload protection, automatic carriage return, and data memory for safe and convenient operation.

Main Technical Specifications 

FAQ
1. What specific parameters can the instrument test?
It can test tensile strength, wet tensile strength, elongation, breaking length, tensile energy absorption (TEA), tensile index, and TEA index, providing a comprehensive evaluation of paper's mechanical properties.
2. What is the advantage of pneumatic clamping over manual clamping?
Pneumatic clamping provides stable and adjustable clamping force, avoiding specimen slippage or premature fracture caused by inconsistent manual clamping. It is especially beneficial for fragile papers like wet-strength or tissue paper, offering higher test reproducibility.
3. Can specimen size be changed? What sizes are suitable?
Yes. The specimen length can be freely set between 30-180 mm according to needs. It accommodates standard specimen sizes and meets the requirements for non-standard or special specimen testing.
4. How can data be exported and reports printed?
The instrument has a data interface and can directly print test reports containing statistics such as average, standard deviation, and coefficient of variation. For exporting data to a computer, please consult our technical team for extended functionality.

5. How should testing speed be chosen? What are the standard recommendations?
Testing speed is typically set within the 1-420 mm/min range based on specimen type and relevant standards. For standard paper tensile testing, please refer to recommended speeds in GB/T 12914 or ISO 1924.
6. Does the instrument require an external air supply? What are the requirements?
It requires a 0.1-0.6 MPa supply of clean compressed air to operate the pneumatic clamping system. A common laboratory air compressor is usually sufficient.
