3. High-speed ARM processor, Degree of automation, fast data collection, automatic measurement, intelligent judgment function, safe and reliable
4. Using 32-bit High Accuracy AD converter and High Accuracy, stable performance pressure sensor to ensure fast and accurate force data collection
5. Linear dispersion diagram of pressure and deformation can be displayed, and pressure can be displayed in real time
6. Adopt modular integrated thermal printer, fast printing speed and convenient paper change
7. Multiple unit options, can be switched between kPa, kgf/cm2, lbf/in2
8. Bilingual operation menu in Chinese and English, and can be switched at any time
Principle
The instrument is designed according to the international universal Mullen method, and realizes automatic measurement through pressure sensor and high-speed ARM processor, collects sample Burst Strength data, and displays pressure and deformation Linear dispersion in real time.
Applications
All kinds of paper, silk, cotton and other non-paper materials
Standards
GB/T454 "Paper Burst Strength Determination", ISO2758 "Paper - Burst Strength Determination"
Steps
Step 1 Place the sample
2. Select units and set parameters
3. Start the test, the instrument automatically measures and displays the results
4. View pressure and deformation Linear dispersion
5. Print out the data
Notice
• Power supply voltage AC 220V +/- 10% 2A 50Hz
• The working environment should maintain indoor temperature (20 +/- 10) ℃, relative humidity < 85%
• Confirm that the sample is placed correctly before testing to avoid unplaced prompts
• Pay attention to the over-range alarm to protect the Sensor
• Regularly check the sealing of the system to ensure that the pressure drop within 1min is < 10% FS
• The film resistance must meet the pressure range of (30 +/- 5) kPa at the protruding height (9 +/- 0.2) mm
