PosiTector® RTR Replica Tape Reader

Digital spring micrometer measures peak-to-valley surface profile height using TestexTM Press-O-FilmTM Replica Tape. The replica tape method is simple, rugged and has good repeatability with relatively low start-up cost. However, conventional micrometer measurements of tape are least accurate at the outer ends of each tape’s range and that is why two tape grade measurements are often averaged. The PosiTector RTR measures with improved accuracy over conventional micrometers because it adjusts for tape non-linearity. Advantages include a reduction in measurement uncertainty, inspector workload, the likelihood of error, the retention of a digital record, and the number of replicas needed to assure accuracy. Conforms to all major international standards including ASTM D4417, SSPC-PA 17, NACE RP0287, ISO 8503-5 and others.
