Hardness tester for steering wheels
Category：Interior Material Tester
Introduction
The Hardness Tester for Steering Wheels is specifically designed to evaluate the comfort and tactile feel of automotive steering wheels. It measures the elasticity and softness of steering wheel materials to ensure compliance with premium comfort standards. This device has been adopted by multiple European automotive manufacturers and is compatible with most passenger car steering wheels. Optional center positioning and auxiliary support brackets enable accurate measurement on irregular-shaped steering wheels.
