Features

DOTE4 digital torque wrench tester, with motor drive
Thanks to motor-driven loading, ideal for calibrating, adjusting and repairing a large number of torque wrenches. Makes work easier too.
The controller has a speed-adjust lever to adjust measurement speed.
Inching can be controlled with the controller dial, making it easy to measure direct reading torque wrenches too.
MD2-SET-SA and MD2-SET-LA kits make it possible to retrofit the DOTE4 with a motor drive. For more information, please contact Tohnichi. *Cannot be retrofit to the DOTE3.
DtRcv (Data Receiver) is a wired data input tool facilitating Excel® data management, and can be downloaded without charge. * ExRcv (Excel Receiver) was upgraded to DtRcv (Data Receiver) in March 2021. * Excel® is a registered trademark of Microsoft Corporation. * To connect DOTE4-MD to a PC, Cable No. 383 or No. 385 (sold separately) is required.

◆ Things to remember when ordering

Japan’s Measurement Law stipulates that in Japan, torque units are to be indicated in SI units (N･m). The law prohibits the use of other units for business or certification purposes in Japan. (There are a few exceptions.)
Tohnichi’s DOTE4-MD2 series testers using SI units (N•m) are for the Japanese market.
For markets outside Japan, Tohnichi manufactures the DOTE4-G-MD2, which permits unit conversions to SI units, metric units (kgf・cm/kgf・m, etc.), and American units (lbf・in, etc.).
