Profile: Precision Devices, Inc. is a manufacturer of instruments for measuring surface finish, surface roughness, surface texture and roundness. We are an ISO 9001:2000 certified company. Our brands include Surfometer™, Profilometer™, IndiRon™, IndiCorder™, and IndiAC™. We design and build bearing test blocks to measure parting line of engine bearings prior to assembly. We also design and build special gages of all types, especially for the gear industry. Our skid-referenced systems are designed to measure normal I.D., O.D., and flat surfaces. The skid-referenced motor drive (piloter) contains a motor which moves the linkarm with the tracer across the surface to be sampled. The tracers have skid pads which establish a reference line. The transducer translates the vertical motion of the diamond tip stylus in relation to the reference line.
