Yokota YET Digital Torque Tester

Capacity 50 / 100 / 200 / 500 / 1000 Nm

Digital Power Tool Tester with Pulse Counter


Management of tightening screws begins on checking fastening tools. YET testers are designed for high precision torque control of mainly impulse type tightening tools. Also usable for angle nutrunners, screw drivers, ratchet wrenches etc. However impact wrenches can be tested also, you should not exceed approx. 2/3 of the testers rated capacity.


Install the YET torque tester in a tool maintenance shop, test laboratory, or at production lines for effective control of fastening such as acceptance inspection, periodical check and torque adjustment. YET torque testers feature a parallel centronics printer port and a serial RS-232C computer interface enabling simultaneous protocol as well as external data recording.
