Classified to DIN EN ISO 6789:2017 Type II Class A, with a factory certificate. Working accuracy: +/- 3 % tolerance of scale set torque. The specification of the standard (+/- 4 %) is exceeded. · Lightweight yet robust (as the housing is made of an aluminium alloy) and resilient, very workshop-friendly · Depending on the application, access is possible from the front (e.g. open-end fitting) or side (e.g. reversible ratchet and socket) · Force to be applied in the middle of the handgrip only - do not use an extension tube as otherwise, inaccuracies can evolve (except for model DXZ where the DREMOMETER has been calibrated and adjusted using the extension tube) · Operation only with end fittings with standardised depth gauges, otherwise inaccuracies can arise. Keep the depth gauges on the certificate in mind. Only use original GEDORE accessories. · Large drive cross-section transfers maximum torques · Extremely low wear attributable to reduced forces in the lever mechanism · Forged lever chain from our own quality forge · Maximum precision even when subjected to extreme continuous use · Long life cycles and tool lives · Easy operation - fast and safe torque tightening · Easy adjustment thanks to attractive adjusting button secured against loss at the end of the handle · With certificate acc. to DIN EN ISO 6789, traceable via in-house DAkkS laboratory to national standards
