GNP-2 Bursting Strength Tester 2025.7.17

Product catalog summary
Introduction
The GNP-2 Computerized Paperboard Bursting Strength Tester is designed to measure the bursting strength of paperboard and corrugated paperboard. It operates by applying hydraulic pressure until the sample ruptures, determining its bursting resistance.

Test Principle
The sample is placed on an elastic film and clamped tightly. Hydraulic fluid is pumped steadily, causing the film to bulge until the sample bursts. The maximum pressure applied is recorded as the bursting resistance.

Standards
The tester complies with ISO2759, QB/T1057, GB/T1539, TAPPI T807, and GB/T6545 standards.

Specifications
  • Measurement range: 250-5600 kPa
  • Resolution: 0.1 kPa
  • Accuracy: ±0.5%FS
  • Pressurization speed: 170±15 ml/min
  • Sample clamping force: 0-2000 kPa adjustable
  • Test system sealing: Pressure drop within 1 min <10% Pmax
  • Power supply: AC110-240V, 50Hz
  • Dimensions: 500×280×540 mm
  • Mass: 47kg
  • Interface: Touch screen with Chinese and English options

Features
  • Reasonable structure with a convenient layout for testing and operation.
  • Advanced technology with a pneumatic automatic clamping system and high-quality materials for durability and accuracy.
  • Easy operation with a touch screen interface and automatic test completion.
  • Fast and efficient testing with pneumatic clamping and chip control.
  • Convenient calibration with a dedicated procedure for easy error correction.
  • Unit selection flexibility between kPa, Psi, and kgf/cm2.

Application
The tester is suitable for cardboard, corrugated cardboard, and is applicable in paper making, packaging, and printing industries.

GNP-2 Bursting Strength Tester  2025.7.17-1

Bursting Strength Tester GNP-2 Introduction GNP-2 Computerized Paperboard Bursting Strength Tester is a basic instrument for testing the bursting strength of paperboard and corrugated paperboard. It is used to test the bursting strength of various paperboards. Test principle Place the sample on the elastic film, clamp the periphery of the sample tightly, and make it bulge freely together with the film. When the hydraulic fluid is pumped in at a steady rate, the film bulges until the sample ruptures, and the maximum pressure applied is the bursting resistance of the sample.

Features ◆Reasonable structure This instrument is the third generation product launched by our company, with core technology and reasonable structure. The clamping system is on the left, and the touch screen LCD display, printing, and operation are on the upper right. It is convenient and fast when testing samples; when the clamping system needs to be operated (such as replacing the film, calibrating the instrument, etc.), it will not have any impact on the circuit control system. ◆ Advanced technology Clamping system: The mechanical aspect adopts an elbow form, and the test sample is not affected...
