The e Series Constant Load Stand with Rigid Coupling eliminates different load variables which occur when hand-testing samples with a durometer. The durometer stand eliminates the variability involved in the downward motion when testing by hand. Smooth operation ensures consistent results. Simply pull the handle forward and let the standard weight apply a constant load to the durometer and the test sample. Using the e-Series durometer stand will increase repeatability of tests. The constant load stand features all metal construction and a safety shield to protect your hands. The stand features a rigid coupling which will easily mount any durometer.
