DeFelsko has introduced a new digital spring micrometer that measures peak-to-valley surface profile height using Testex Press-O-Film Replica Tape

The new PosiTector RTR Replica Tape Reader provides improved accuracy by adjusting for tape non-linearity, the manufacturer says.

DeFelsko notes that the replica tape method of measuring surface profile is widely used and accepted. The test is "simple, rugged and has good repeatability with relatively low start-up cost," DeFelsko says.

DeFelsko says its new Replica Tape Reader offers better accuracy by adjusting for tape non-linearity.

"However," the company adds, "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 new RTR unit allows the user to retain a digital record, providing "a reduction in measurement uncertainty, inspector workload, the likelihood of error, and the number of replicas needed to assure accuracy," according to DeFelsko.

The PosiTector RTR conforms to ASTM D4417, SSPC-PA 17, NACE RP0287, ISO 8503-5 and other international standards.
