The PosiTector RTR series measures and records surface profile parameters using Testex™ Press-OFilm ™ Replica Tape. It uses imaging sensors to measure the peak density (Pd) information contained in replica tape in addition to peak height. Advanced models are able to generate 2D/3D images and surface data file (SDF) files of the replicated surface. A high-resolution SDF can be imported into third-party rendering software for further examination. Call 800/448.3835.
