Abstract: An apparatus for testing hardness of elastomeric material comprising a pivotally mounted beam assembly for measuring deformation of the material when a calibrated mass is applied thereto. A horizontal anvil member supports the material being tested which is selectively positioned on the anvil member in accordance with a cross-sectional dimension of the material. The calibrated mass or weight is slidably positioned on the beam assembly also in correlation with said dimension. A measuring gauge measures the beam assembly when the test material is gripped between the beam assembly and anvil member, and indicates hardness on a scale correlated to the measured cross-sectional dimension of the material. The gauge and a lateral extension of the beam assembly are magnetically coupled.
