ASTM D3574 Digital Foam Density Tester Sponge Density Testing Machine for Polyurethane Foam

Sponge Density Tester is a high-precision laboratory testing instrument specially developed for measuring the apparent density and bulk density of porous elastic materials such as polyurethane foam, sponge, latex foam, and cellular rubber materials.

Suitable for polyurethane foam, sponge, latex foam, cellular plastics, and porous elastic materials

Adopts Archimedes principle combined with electronic precision weighing technology

Fast digital density calculation without manual computation

High-precision imported sensor ensures stable and reliable measurement performance

Supports density, volume, water absorption rate, porosity, and closed-cell ratio testing

Automatic water temperature compensation improves measurement accuracy

Special anti-floating frame suitable for low-density materials below 1g/cm³

Can use water or alternative liquids as testing medium

Widely used in furniture, mattress, automotive interior, sponge, and foam manufacturing industries Optional printer available for direct printing of testing reports

Compact desktop structure with easy operation and high testing efficiency

Dongguan Huakai Testing Equipment Technology Co., Ltd. is a professional manufacturer specializing in reliability and environmental testing equipment, with over a decade of industry experience. Unlike trading companies or OEM resellers, we are a vertically integrated manufacturer - owning our R&D, production, and quality control under one roof.
Every Huakai product is designed, engineered, and manufactured entirely in-house, giving us full control over precision, lead times, and customization depth that most suppliers simply cannot match.
Self-Developed, Not Sourced Our in-house engineering team holds multiple patents. We develop our own control systems, thermal management modules, and test software - not dependent on third-party core components that limit flexibility.
Fast Delivery Without Compromising Accuracy Standard models ship in as little as 7--15 business days. Our streamlined manufacturing process - not shortcuts - makes this possible.
Customization That Actually Goes Deep When clients require non-standard chamber sizes, unique temperature profiles, or integration with their existing data acquisition systems, we engineer a real solution - not just a relabeled catalogue product.
Global Compliance Built In All products are CE certified and comply with IEC, ASTM, MIL-STD, and GB standards. Our chambers have helped clients pass certifications across consumer electronics, EV batteries, automotive components, aerospace, and medical devices.
After-Sales You Can Rely On Factory engineers - not third-party agents - handle all technical support. Spare parts are stocked and dispatched within 24 hours. Remote diagnostics available for international clients.
