Purpose

The LR-A381 computer-controlled horizontal tensile testing machine is a specialized instrument designed for testing the tensile strength of paper. Its measurement range includes 30N, 300N, 500N, and 1000N, and is suitable for various types of paper and paperboard for testing. Among them, the 30N measurement range is particularly suitable for detecting the wet strength of sanitary paper, napkins, and hand-toweling paper, and fully complies with the wet strength requirements in the wet wipe standard GB/T27728-2011.

Compliant with standards

ISO1924/2, GB/T12914, GB/T 22898, GB/T1040, GB2792, GB/T14344, GB/T2191, GB/T2171, QB/T1053, GB/T465.2, GB/T24328.4-2020

Product features

1. High precision and repeatability

The instrument is equipped with high-precision force sensors, with an accuracy control of <0.5% at factory, which is superior to the ISO standard of ±1%. Due to the use of stepper motors and precise ball screw transmission, combined with reasonable design and precise mechanical processing, the instrument ensures its repeatability.

2. Long lifespan

The precise ball screw transmission, aluminum alloy panel, high-quality machining process and reasonable design ensure the durability of the instrument. Our professional design and programming team can also upgrade the instrument.

3. Wide application range and complete functions

Several measurement ranges are available for selection, enabling this model instrument to be applicable to all paper and paperboard. Moreover, it has complete functions: it can detect the tensile strength, tensile modulus, elongation, elongation rate, breaking length, tensile energy absorption, tensile index, tensile energy absorption index, and breaking time of the paper.

4. Convenient to use and easy to operate

The touchscreen displays in Chinese, with a friendly human-machine interface for operation. The test is fully automated, with statistical processing functions for test data, micro printer output, and can also be operated through a computer. When connected to a computer, in addition to automatically remembering and storing results, it can also display the tensile curve and save it.

5. Fast and efficient during testing

Pre-set clamping distance and test speed make the testing faster and more efficient.

6. Convenient for measurement and calibration

The force sensor is located above and connected to the upper clamping head. The user or the metrology and calibration department (third party) can easily calibrate the instrument's indication error by hanging the standard weight on the upper clamping head.
