Gauge Blocks for the Calibration of Comparators
To calibrate both TESA gauge block comparators UPD and UPC, we recommend the
use of the gauge block set described hereafter. The 9-piece set is all so required
for calibrating TESA UPD.

Set composition including 11 steel gauge blocks, class K
Each pair is in full compliance with:

• EAL-G21 – Calibration of gauge block comparators – European cooperation for Accreditation of Laboratories
• DKD-R 4-1 – Guidelines of the German Calibration Service (DKD) for the calibration of gauge block comparators.
