Product outline
Ideal torque meter for torque monitoring of screwdriving machines and power tools such as nutrunners.
Ensures high speed and accurate torque measurement during tightening with UTMⅡ.
Can be used with portable torque monitor TM400 for on-site calibration.
Ensures high speed and accurate torque measurement during tightening with UTMⅡ.
Can be used with portable torque monitor TM400 for on-site calibration.
■ Capacity: 10 N m/ 20 N m/ 50 N m/ 100 N m/ 500 N m
■ It is ideal to monitor torque of nut runners (fastening tools)
■ With the high accuracy and high-speed response of UTMⅡ
torque fluctuation can be monitored while tightening nuts.*
Torque: UTMⅡ(W)
Torque + Angle: UTMⅡ(WR)
*Note: Please do not use it with impact wrenches.
■ Torque can be easily checked by simply
inserting and tightening it between
the nut runners output shaft and socket.
Torque can be monitored easily just by setting the sensor between socket and shaft of a nut runner.
- 0.03％ high accuracy & stable
Non-linearity of 0.03% with outstanding zero stability.
Small torque can be measured at high accuracy. - Avoid data loss
No slip-ring ensures that torque can be measured consistently.
Best fit for angular tightening (rotation angle method)! UTMⅡ(WR)
By monitoring rotation angle and torque at the same time, accuracy and consistency of torque tightening can be checked.
- 3600 torque pulses per rotation with 0.1 degree resolution※
Can be used for on-site calibration with 0.1 degree resolution!
※When using TM400 - Portable torque monitor TM400（Optional accessories）
Portable type with built-in battery. Changes in torque can be displayed with respect to angle.
Peak value of torque and angle can be measured and saved in internal memory.
