The mattress hardness testing machine is used to evaluate the hardness. It is widely applied to industries of foam products, mattress, car seat etc. It is used in laboratory for quality control in production line.
Universal hardness and hardness measurements are based on a physical property called indentation force deflection. The hardness is calculated by determining the ratio of the thickness after being compressed and the original circular indentation force. The computer receives the signal from the sensor and record the extent of indentation when the platen stresses on the specimen. In order to compare the test results, the size and thickness of specimens must be the same.
