A digital bursting strength tester is a laboratory instrument used to measure the bursting strength of materials such as paper and corrugated boxes. It utilizes digital technology to provide accurate and precise measurements. Here are some key features and specifications commonly associated with digital bursting strength testers:
1. Digital Display: Digital bursting strength testers are equipped with a digital LED display that shows the measured bursting strength in units such as kg/cm² or psi.
2. Hydraulic Load: These testers apply hydraulic pressure under a rubber diaphragm to exert force on a specific area of the sample being tested. The pressure is gradually increased until the sample bursts.
3. Accuracy and Resolution: Digital bursting strength testers typically offer high accuracy, often within 1% of the entire range. The resolution, or least count, is usually around 0.1 kg/cm².
4. Test Capacity: The capacity of a digital bursting strength tester can vary, ranging from 20/50 kg/cm² to 7000 kPa, depending on the model and manufacturer.
5. Test Standards: These testers adhere to industry standards such as ASTM D 3786-01, ASTM D 3786 80A, and ISO 1060 PART-1 1987.
6. Additional Features: Some digital bursting strength testers may have additional features, such as the ability to calculate bursting factor, preset tighten strength, or connectivity with thermal printers or digital lab management systems.
It's important to note that the specific features and specifications of digital bursting strength testers may vary among manufacturers and models. For more detailed information, it is recommended to consult the product documentation or contact the manufacturer directly.
