Mid Range Torque Watch
Gauge Series
Model 651
DESCRIPTION
The 651 mid-range torque watch gage series provides accurate
measurement of low static torque. A 1/4 inch keyed chuck
provides a simple means of coupling to the device under
measurement.
The 651 Series utilizes a calibrated spring, shaft, and pointer
assembly within a rugged steel and aluminum housing. The unit
can measure torque in either a clockwise or counterclockwise
direction. Internal stainless steel rotation stops help prevent
damage from over-torque up to two times the normal range.
