YT-SLD1000 Electronic Tearing Tester

Electronic Tearing Tester is an intelligent testing instrument used to determine the tearing performance of paper, paperboard, and other low-strength sheet materials. It is suitable for fields such as papermaking, packaging, printing, quality inspection, scientific research, and colleges and universities.

The instrument adopts the pendulum method measurement principle and integrates functions such as pneumatic sample clamping, automatic sample pre-cutting, automatic pendulum release, tear measurement, pendulum braking, and automatic reset. The operator only needs to place the sample and start the test, and the instrument will automatically complete the entire test according to the set procedure, greatly simplifying the operation steps, reducing manual intervention and waiting time, and is especially suitable for continuous and batch testing, effectively improving testing efficiency and operational convenience.

A sample that has not been pre-cut is placed between the fixed clamp and the pendulum clamp. After the instrument is started, the sample is automatically clamped and pre-cut according to the specified slit length, so that the sample retains the standard tearing distance. The pendulum is then automatically released, and the remaining part of the sample is torn by the pendulum under the action of gravity. Based on the change in potential energy of the pendulum before and after tearing the sample, the instrument calculates the energy consumed during tearing, and automatically obtains the tearing strength test result in combination with the calibration parameters and the number of sample layers. After the test is completed, the instrument automatically brakes and returns the pendulum to its initial position.

Paper, cardstock, low-strength paperboard, packaging paper, certain films, nonwoven fabrics, and other low-strength sheet materials.

Measuring tear strength

●  One-Key Fully Automatic Testing: After the sample is placed and the test is started, the instrument automatically completes clamping, pre-cutting, release, measurement, braking, and reset.

●  Pneumatic Automatic Sample Clamping: The sample is clamped quickly and stably, reducing the influence of differences in manual clamping force on test results.

●  Automatic Precise Pre-Cutting: A pre-cut slit of the specified length is automatically formed to ensure consistency of the remaining tearing distance.

●  Automatic Pendulum Release: The pendulum is released by an automatic mechanism, reducing test differences caused by manual release timing and operation.

●  Automatic Pendulum Braking and Reset: After the test is completed, the pendulum automatically brakes and returns to its initial position, improving continuous testing efficiency.

●  Multi-Range Testing: Supports A and B range switching to meet the testing requirements of materials with different tearing strengths.

●  Unit Switching: Supports switching between test units such as mN and gf.

●  Multiple Data Output Methods: Supports functions such as thermal printing, USB flash drive export, and USB/Wi-Fi communication.

●  Power-Off Data Protection and Online Upgrade: Supports power-off saving of test data, and the system and screen software support upgrades via network or USB flash drive.

●  Yante Instrument Testing Platform Software (Optional): Supports communication with a computer via Wi-Fi or USB, enabling instrument control, test parameter setting, and test operation on the software side, as well as real-time monitoring of the testing process, automatic data acquisition, historical data storage, test curve display, and comparative analysis of multiple sets of data. One set of software can connect to and manage multiple testing instruments under Yante, facilitating unified management of instruments, testing processes, and testing data in the laboratory.

●  QMS Quality Management System (Optional): Supports rapid upload, query, export, statistical analysis, and full-process traceability of testing data. It can manage samples and associated test results according to testing tasks, and provides functions such as data unit conversion, result judgment, and test report generation and output, realizing integrated management of testing tasks, instrument data, quality analysis, and reports.
