Geomembrane tear strength tester

Standard

• ASTM D7176(Standard Test Method for Determining the Resistance of Geomembranes to Slow Steady-State Strain)
• ISO 17548(Geosynthetics - Determination of Tear Resistance)
• GB/T 17642(China National Standard for Geomembrane Mechanical Properties)

Product Advantages

1. Unmatched Precision
   • High-resolution pressure sensor (±0.1 kPa accuracy) captures even subtle membrane deformations, critical for HDPE, LDPE, and PVC geomembranes.
2. Automated Testing Protocols
   • Programmable test cycles simulate slow strain (0.1–10 mm/min) and rapid fracture events, replicating real-world installation and operational stresses.
3. Safety First Design
   • Explosion-proof test chamber, emergency pressure relief valve, and laser-guided specimen alignment minimize operator risk.
4. Industrial-Grade Durability
   • Stainless steel test cavity, corrosion-resistant hydraulic system, and anti-vibration feet ensure long-term reliability in demanding labs.
5. User-Centric Operation
   • 10.1-inch capacitive touchscreen with multilingual support (English, Spanish, Arabic, Japanese) and AI-powered data analysis.

Product Features

• Multi-Mode Testing:
  • Constant Pressure Test: Applies static load to assess long-term creep resistance.
  • Gradient Pressure Test: Increases pressure at 0.1–10 kPa/s to simulate sudden hydraulic impacts.
  • Cyclic Loading: Replicates tidal/wave pressure fluctuations for coastal lining applications.
• Real-Time Monitoring:
  • High-speed camera (1,000 FPS) captures fracture initiation and propagation, with thermal imaging for localized stress analysis.
• Data Management:
  • Cloud-compatible software stores 10,000+ test results, generates ISO/ASTM-compliant reports, and supports barcode scanning for sample tracking.
• Universal Specimen Compatibility:
  • Adjustable clamps accommodate geomembranes up to 2mm thick, including textured and smooth surfaces.
