DeFelsko Corp. has released the PosiTector® RTR replica tape reader, a new digital spring micrometer that measures peak-to-valley surface profile height using Testex™ Press-O-Film™ Replica Tape.
The replica tape method of measuring surface profile 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.
