Residual Concavity Meter
Model: BC-AXD-4085
Applicable fields
The residual concavity meter is a commonly used equipment for testing the residual concavity of PVC flooring and WPC rubber flooring.
Working principle
Using weights and some equipment components that match the required weight, directly apply them to the surface of the sample, and use the depth of pressure applied over a certain period of time as the standard for determining the degree of indentation.
