Overview
The PN-ST500F computer stiffness tester is a multi-functional smart instrument designed to measure the bending stiffness of paper, Cardboard and Miscellaneous sheet Non-metallic materials with a thickness of less than 2mm. Stiffness is an important indicator of the bending strength of materials. The instrument provides scientific data support for optimizing product performance and cost control by precisely controlling the test angle and time. It has functions such as fully automatic testing, Touchscreen operation and data statistical analysis, making it an ideal tool for modern quality management.
Features
1. Adopt new module circuit design, with WIFI Internet of Things function, test data can be uploaded to Cloud as a Service for management and analysis.
2. The test angle can be arbitrarily set between 1 ° and 90 °, and standard angles such as 7.5 ° and 15 ° are supported.
The test time can be set by any number between 3 and 30 seconds.
4. The test angle change is automatically controlled by the motor, which has high measurement efficiency and reduces human error.
5. Supports three bending length tests: 50mm, 25mm, and 10mm.
6. With automatic zero adjustment function, there is no need to manually rely on the sample before testing.
7. With measurement statistics, printing and Measurement time setting functions.
8. After the test is completed, it can return to the starting position at high speed, and the return speed can be adjusted between 1 and 12.
Principle
Driven by a motor, the instrument bends a sample of a specified size to a set angle, and calculates the stiffness value of the material by precise measurement of the force or moment required to complete the bending process. The test process is fully automated, and the stiffness and time Linear dispersion are displayed in real time to ensure the accuracy and Repeatability of the measurement results.
Applications
Paper stiffness testing, Cardboard stiffness testing, Miscellaneous flake Non-metallic material flexural strength testing
Standards
GB/T 22364、GB/T 2679·3、ISO 2493、ISO 5628
Steps
1. Prepare samples that meet the requirements.
2. According to the test standards or requirements, set the bending angle, test time, bending length and other parameters on the Touchscreen.
3. Place the specimen on the test fixture.
4. Start the automatic test program, and the instrument will automatically zero and complete the bending test.
5. After the test is completed, the instrument automatically returns to the starting position and displays the test results on the screen.
6. Data can be counted, stored, or printed out through the instrument.
Notice
• Please ensure that the instrument works in an environment with indoor temperature (20 +/- 10) ° C and relative humidity < 85%.
• Power supply voltage is within (100~ 240) VAC range before use.
The thickness of the sample should be less than 2mm.
Before testing, please set the parameters correctly according to the standards or requirements.
• Maintain instruments regularly to ensure Measurement accuracy.
• Do not forcibly interfere with the automatic operation of the instrument during operation.
