Tohnichi CEM3-G-BTA Digital Torque & Angle Wrench

Capacity 10 / 20 / 50 / 100 / 200 / 360 / 500 / 850 Nm

Wireless Data Transfer Torque & Angle Wrench

Industrial grade digital torque wrench with angle measurement function. Also able to detect double tightening and “bite”. Provides Pass/Fail judgements of tightening torque and final angle, once you set threshold values. Built-in Bluetooth® module makes data collection easy.

Applications

Tightening tasks requiring torque and angle control.
Detects two rounds of tightening to prevent this human error (Pokayoke).
Detects increased torque due to insufficient rotations from “biting (seizure)” during tightening.
Tightening Torque Data Management.
Detects tightening abnormalities such as “forgetting assembly of spring washer”.

Features

Records in memory and outputs torque and angle at final tightening.
Capable of performing Pass/Fail judgements of tightening torque and angle.
You can set torque and angle required for Pass/Fail judgements.
Uses torque and angle values to detect double tightening (Pokayoke error-proofing system).
Built-in Bluetooth® module to transmit data wirelessly.
Capable of managing both wired and wireless (Bluetooth®) tightening data.
