Overview
JINGWEN JW-117 softness tester is a test instrument that simulates the softness of the hand. It is designed according to the relevant provisions of the national standard GB8942 "Determination of Paper Softness". The instrument is mainly used for the softness measurement of sheet-like soft software materials such as medium and high-grade paper, Tobacco flakes, fiber fabrics, etc. It adopts microcomputer-controlled digital circuit technology and is equipped with a humanized touch screen display and operation interface. It has the advantages of professional technology, complete functions, reliable performance and easy operation.
Features
1. Designed according to the national standard GB8942, it is highly professional.
2. Digital circuit technology controlled by microcomputer, reliable performance.
3. Equipped with a user-friendly touch screen display and operation interface, it supports both Chinese and English operating systems.
4. Measurement range (10~ 1000mN), Precision high (+/- 1%).
5. Provide a variety of sample table slot-die widths (5mm, 6.35mm, 10mm, 20mm).
Principle
The instrument is tested by simulating the softness of the hand. The probe is pressed into the sample at a speed of 1.2mm/s to a specified depth (8 + 0.5mm). Within 15 seconds of measurement, the system measures and calculates the force value of the sample against bending, thereby obtaining its softness value.
Applications
Paper making, scientific research, Quality control and other industries and departments
Standards
GB8942 "Determination of paper softness"
Steps
Connect the power supply (AC 220V +/- 22V, 50Hz).
2. Select or set test parameters (e.g. slot-die width) via the touchscreen.
3. Place the specimen on the slit of the specimen table.
4. Start the test, the instrument automatically completes the probe indentation and measurement process.
5. Read test results and Linear dispersion on the touch screen.
Notice
• Power supply voltage in AC 220V +/- 22V range.
• Select the appropriate slot-die width according to the specimen type.
• When operating, pay attention to the parallelism error on both sides of the sample table slot-die should be less than or equal to 0.05mm.
• Encasement and internal cushioning materials are used for instrument transportation, so be careful when handling.
The service life of the touch screen is about 50,000 hours, please avoid improper operation.
