Replica Tape Readers for use with Testex tape

Testex Replica Tape

The PosiTector Replica Tap Reader gages measure and record surface profile parameters using replica tape.

For use with Testex™ Press-O-Film™ Replica Tape - Digital spring micrometer measures and records peak to valley surface profile height using replica tape.

Positector Replica Tape Reader Case

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.

RTRH Peak Height Technical Data
Range: 20-115 µm (0.8 - 4.5 mils)
Accuracy: ±5 µm (±0.2 mils)

PosiTector® RTR3D

  • Conforms to ASME B46, ASTM D4417, ISO 8503-5, NACE SP287, SSPC-PA 17, SSPC-SP5, SP6, SP10, SP11-87T and others.
  • Measures peak height (HL) and common 2D/3D profile parameters such as Ra, Rz, Sq, Spd and more
  • Certificate of Calibration (containing Ra and Rt measurements) showing traceability to an accredited national laboratory included
  • Calculates and records all fourteen 2D and 3D parameters with each measurement
  • Apply short and long cutoff filters and discard lengths to optimize the analysis for a specific application
  • Orient the 2D trace between horizontal, vertical and diagonal (XY, YX)
