Precision Friction Measurement Apparatus

Model HV-EXP2651
Technical Description The precision measuring unit is used to determine coefficients of friction experimentally. Several different pairs of materials with varying surface finishes can be investigated. During this process, the specimen under examination is stationary and the supporting friction surface is pulled past it. In this way a stable force measurement is made over the measuring range 02N with a resolution of 0.05N. The force dial gauge is equipped with an air damper to compensate slip-slap effects to a large degree. The supporting friction surface is driven using an electrical synchronous motor. The drive provides two constant speeds. The normal force can be changed by adding weights. The sturdybenchtop unit was specially designed as a student experiment..
