Key Features & Advantages

  • Robust Tungsten Carbide Core
    Manufactured with ultra-hard, low thermal expansion tungsten carbide for exceptional wear resistance and stable performance across varying ambient temperatures (20±5°C).

  • Precision Weight Loading System
    Low-center-of-gravity design with direct weight application ensures smooth piston movement, minimal pressure fluctuation, and highly accurate measurement results.

  • High-Viscosity Performance
    Low-viscosity isooctyl sebacate medium enables superior sensitivity, particularly in high-pressure applications exceeding 25 MPa.

  • Intelligent Monitoring
    Non-magnetic stainless steel weights combined with integrated piston displacement sensors provide real-time position tracking and clear visual feedback.

  • User-Friendly Operation
    Wide measuring range with precisely engineered pressure regulation allows effortless operation across all pressure levels, including maximum capacity of 250 MPa.
