The Mattress Firmness and Hardness Testing Machine is designed to evaluate the hardness and firmness levels of mattresses. It applies load using a rigid circular plate with a convex spherical bottom, records the load-displacement curve, and analyzes data to determine mattress hardness value and grade. The system adopts aluminum alloy structure for durability and aesthetics, and features a high-precision intelligent ARAM controller with dedicated testing software, which operates under Windows system for full software control and easy operation.
Functions and Applications
* Applies spherical convex rigid plate to test mattress hardness and firmness
* Records load vs. displacement curves for precise hardness grading
* Equipped with intelligent ARAM controller and dedicated Windows-based software
* Widely used in mattress manufacturing, quality control, and product certification
