TORQUE WRENCH > TECNOGI > MECHANICAL TORQUE WRENCH WITH VARIABLE GEOMETRY > SERIES 900F   Mechanical torque wrenches with variable geometry Torque wrenches of new concept, designed and manufactured to exceed performances required by EN ISO 6789:2003 Fast and easy setting. It doesn't need to turn back to the minimum scale value after being used Long life accuracy and repeatability Pateneted The wrench works with a "variable arm clicker mechanism". Torque variations are obtained not by screwing or unscrewing a spring (the critical component in a standard click type wrench) but by a variation of levers positions. The spring inside works always in the same condition independently of torque selected. This innovative system guarantees endurance and stability. Endurance Test Cycles made to the maximum value (350 Nm): 40.000 Calibration check: every 1000 in first 10.000 cycles and every 5.000 in the followings. With reversible 72 teeth with ratchet head, universal fittings 9x12, 14x18 or 16 mm spigot end Quick and precise slide adjustment by unscrewing the knob and glinding the slider on the scale to the required value With granduated scale in Nm and Lbf.ft or pre-set (the desired torque must be set using a torque analyzer). High repeatibility and high reliability. Double signal when set torque is reached: acoustical click and effort decrease Ergonomic handle. Guaranteed accuracy in accordance with EN ISO 6789:2003 Calibration certificate with SIT traceability ± 3% Model Nm Lbf. ft ATTACCO DRIVE mm Kg 906F 10-60 7.5-44 9x12 380 1.00 910F 20-100 15-70 9x12 445 1.10 920F 40-200 30-150 14x18 450 1.10 930F 60-350 45-260 14x18 580 1.40 Available aslo pre-set   The products shown above are only a small part of series, please contact us for your enquiry.
