ISO 2781 Rubber Density Tester CF8389

The CF8389 Rubber Density Tester provides accurate and rapid specific gravity and density measurement of vulcanized rubber, thermoplastic elastomers, and similar materials using the water displacement method per ISO 2781 and ASTM D297. Integrated electronic balance with below-weigh hook eliminates manual calculation and ensures consistent, operator-independent results.

Key Features

ISO 2781 & ASTM D297 Compliant: Water displacement method with automated density calculation for rubber and elastomeric materials.
High-Precision Electronic Balance: 0.001g readability with maximum capacity of 310g for both small laboratory samples and larger production specimens.
One-Touch Operation: Measure sample weight in air, then in water with single button press. Automatic density calculation with temperature-compensated water density.
Integrated Water Tank: Built-in temperature-controlled water tank with ±0.5°C stability ensures accurate buoyancy measurement per standard requirements.
