SURFACE PLATE CALIBRATION PRODUCTS
RAHN PLANEKATOR KITS - used in the calibration of surface plates and other plane surfaces
Size in Inches	Total Weight of Kit	Straight Edge Accuracy
24”	45 lbs	.000050”
36”	75 lbs	.000075”
48”	115 lbs	.000100”
Each Planekator Kit includes an autocollimator-calibrated precision granite straight edge,
a heavy-duty case, two mounting supports for the straight edge and a calibrated .000020" dial indicator.
The straight edge is supplied with a correction tape indicating the accuracy at 1" intervals and a calibration
certificate that meets the requirements of ISO/IEC 17025 and is NIST Traceable.
Selecting Straight Edge Length:
The Planekator straight edge should be at least equal to the full width, and at least equal to 50% of the length
of the largest surface you will be inspecting.  For example, a 36" planekator straight edge can be used to
calibrate any surface up to 36" x 72".
RAHN REPEAT-O-METER - for calibrating the repeatability of surface plates and other plane surfaces
No masters.  No calibration necessary.  Quickly scan your plates for wear spots that may affect the
accuracy of your measurements.
STANDARD REPEAT-O-METER
Can be used with any 0.375" stem indicator.
Indicator and case sold separately.
