Torque measurement range: 0.5 ~ 10 N・m (*) Tohnichi’s smallest digital torque wrench (*two models in the series). The optional Bluetooth module makes it easy to manage data on a computer or other device.

Shown with a QH6D Ratchet Head (standard accessory) connected to CES5NX6D

Equipped with a high-luminance LED. Permits confirmation of current tightening condition and pass/fail judgments from a wide range of angles. The high-luminance LED is especially useful in dark working conditions.

Tightening-abnormality detection: monitors torque and angle to detect tightening abnormalities such as scuffing, missing parts, missed tightening (or double tightening), and O-ring nibbling, to prevent the delivery of defective products to clients.

Use a USB to output memory data. Permits no-fee use of the data input tool DtRcv (Data Receiver) for data management in Excel® worksheets.

Attach the optional Bluetooth module (picture on the left) to wirelessly transmit tightening and inspection data to a computer. *The M-CES-BT Expansion Module is easy to attach.

Use the Tightening Data Management System (TDMS) software (sold separately) to transmit conditions at each tightening location to the torque wrench, and to transmit pass/fail data after tightening to a computer. (TDMS was upgraded to Version 3.10 in June 2023. Now also supports the compact Digital Torque Wrench CES series (when installed on M-CES-BT).)

For tightening and inspection work in low torque regions, such as cable grounding, and plastic or ceramic screws/bolts.

Useful in confined spaces and height-restricted locations where tightening with a torque screwdriver or conventional torque wrench is difficult.

For tightening work involving fragile apparatus, such as sensors and semiconductor manufacturing equipment.

Application

  • For tightening and inspection work in low torque regions, such as cable grounding, and plastic or ceramic screws/bolts.
  • Useful in confined spaces and height-restricted locations where tightening with a torque screwdriver or conventional torque wrench is difficult.
  • For tightening work involving fragile apparatus, such as sensors and semiconductor manufacturing equipment.

Features

  • CES/CES-G monitors torque and angle to prevent the delivery of products with defective screw/bolt tightening.
  • Equipped with a high-luminance LED. Permits confirmation of current tightening condition and pass/fail judgments from a wide range of angles. The high-luminance LED is especially useful in dark working conditions.
  • Tightening-abnormality detection: monitors torque and angle to detect tightening abnormalities such as scuffing, missing parts, missed tightening (or double tightening), and O-ring nibbling, to prevent the delivery of defective products to clients.
