LINEAR AND ROTARY POSITION
Torque Watch
Guages
The Torque Watch, an industry mainstay when an accurate indication of rotary force is necessary, is
simple to use, requiring no special tools or setups. Available in three models they cover ranges from
0.003 to 200 inch-ounces. Attach the gauge to the device being measured, and simply rotate it, for a
direct reading dial.
Protection against over-torque is provided by a stainless steel internal rotation stop. The low range
366 Series will prevent damage from over-torque up to three times the normal range, whilst the mid range
641 Series and the high range 940 Series will prevent damage up to twice the normal range.
Models are available in standard (ounce inch), metric (gram centimeter) and System International
(Newton meter) measuring options.
366 Series
Low range
0.003 - 0.60 oz in
The Series 366 Torque Watch accurately measures
very low torque. Three miniature adapter chucks
allow simple coupling to the device being
measured.

651 Series
Mid range
0.05 - 40.0 oz in
The Series 651 Torque Watch 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 Series 940 Torque Watch accurately measures
torque in values that range form 15.0 to 200 oz/in.
A 3/8 inch keyed chuck and 3/8 inch square socket
driver adapter provide a simple means of coupling
to the device under measurement.
