Verification and calibration of handheld force gauges designate with the tradename Atorn (Hahn+Kolb GmbH, Germany), traceable to the international PTB/DKD/ILAC standards. The comprehensive calibration certificate contents the calculation of uncertainty, the confirmation and advise for calibration intervals according the chosen accredited calibration procedures e.g. VDI/VDE directive 2624 sheet 2.1 or DAkkS-DKD-R 3-3 (B).
The calibration for tensile and compression force (pull and push direction) is performed on an automated calibration machine with direct staggered mass application for forces up to 1000N. The lowest resolution is 0,2 N for force gauges with 2 N measuring range. Force gauges with nominal measuring range higher 1 kN are calibrated on a machine with transfer standards up to 250 kN.
Please consult the page "Calibration Laboratory for Force" and the part nos. CAL-100 or CAL-210 in order to check which measuring ranges of the calibration stands are covered by the accreditation in relation to the nominal force range of your gauge.
