Rubber, Plastics and Elastic Materials Density Tester
Density Meter | Densimeter | Specific Gravity Tester
The Rubber, Plastics and Elastic Materials Density Tester is a high-precision analytical instrument engineered to measure the density, specific gravity, porosity, and absorption properties of rubber, plastic, elastomers, and a wide range of related solid materials. Operating on the time-tested Archimedes' Principle (buoyancy method), and supported by advanced techniques such as vacuum saturation and boiling saturation, the TTD-PY series delivers fast, repeatable, and laboratory-grade results.
Every model in the series is built around a high-resolution digital balance, an infrared temperature sensor for automatic water-temperature compensation, and an intuitive direct-reading display that eliminates manual calculation. Operators can instantly view bulk density, wet density, porosity, absorption, apparent density, open pores, closed porosity, total porosity, and even two-group mixture ratios — turning a traditionally tedious procedure into a one-touch operation.
Compliant with international standards including ASTM C20, C127, C128, C134, C135, C437, C357, AASHTO T 84, JIS K6530, ISO 1183 / 2781, and a complete range of GB/T specifications, the Torontech TTD-PY family is trusted in quality-control laboratories, R&D centers, and production facilities worldwide for delivering reliable measurements that meet the most demanding compliance requirements.
