Positector® RTRH
- Conforms to ASTM D 4417, ISO 8503-5, NACE RP287, SSPC-PA 17, SSPC-SP5, SP6,
SP10, SP11-87T and others
- Measures peak height (HL)
- Automatically subtracts the 50.8 µm (2 mil) incompressible film from all readings
- Minimizes inspector workload by reducing the number of replicas needed to ensure accuracy
- Produces a more accurate peak-to-valley height measurement (HL)
- Certificate of Calibration showing traceability to PTB included
- Continually displays/updates average, standard deviation, min/max height and number of readings while measuring
Linearized Peak Height Measurement (HL)
Coarse and X-Coarse replica tape share a 38 - 64 µm (1.5 - 2.5 mil) "overlap" region. Measurements with analog micrometers require a complicated linearization procedure - averaging the two grades of replica tape to achieve reasonable accuracy. With a single measurement, the PosiTector RTR produces a linearized peak-to-valley height measurement (HL), accurate over the full range of Coarse and X-Coarse tapes. There is no need to average two or more replicas. |
