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.
