The PosiTector SHD probe consists
of an indentor, calibrated spring and a
presser foot.
Two probe models are available for
measuring on a variety of materials:
PosiTector SHD A (Shore A)
soft rubber, elastomers, neoprene, silicone, etc.
PosiTector SHD D (Shore D)
hard rubber, epoxies, hard plastics, PVC, acrylic, etc.
Calibration and Verification
Calibration and Verification
Two steps ensure best accuracy...
1. Calibration - typically performed by the manufacturer. All
probes include a Certificate of Calibration.
2. Verification of Accuracy - typically performed by the user on
known reference standards such as the included test block.
Calibration
Calibration is the high-level, controlled and documented process
of measuring traceable calibration standards over the full
operating range of the probe, and verifying that the results are
within the stated accuracy of the probe. Calibrations are
performed by the manufacturer, their authorized agent, or by an
accredited calibration laboratory in a controlled environment using
a documented process.
Verification
Verification is an accuracy check performed by the user on
known reference standards. A successful verification requires the
Gage to read within the combined accuracy of the probe and the
test blocks. Instrument operation may be verified with the
included test block. Place the test block on a flat, hard surface
and take three to five readings. The measurement points should
be at least 6 mm (0.24") apart. If the average of those readings
is outside the combined accuracy of the test block and gage, the
gage may require service.
