plus angle tightening sequences. Will also
accumulate angle measurement when multiple turns
are required, ideal for when access is limited.
Preset desired torque levels or track peak and
working torques using simple push-button menu.
Selectable read-out in Nm, lb.in, lb.ft, kgf.m or
degrees. Reversible Chrome Vanadium 72-tooth
ratchet allows torque reading in either direction.
