TOHNICHI; Japan

Dial indicator torque wrench DB/DBE/DBR series

Model: DBE2100N ( 200~2100 N.m)

The Tohnichi DBE2100N-S (200~2100 N.m / 20~210 kgf.m) is primarily used for high-capacity torque quality inspection (auditing) and precision tightening of critical large fasteners.Because it is a dial-indicating wrench with a memory pointer, it is treated as a measuring instrument rather than a standard assembly-line click wrench DBE2100N-S [overall length 2140 mm with extension bar]

• Measuring Residual Torque (Quality Auditing): Checking already-tightened bolts on a machine to see if they have loosened or if they meet safety specifications.
• Peak Torque Logging: The built-in red memory pointer captures and holds the highest torque value reached, allowing an inspector to read and log the exact data point after force is released.
• High-Precision Tightening: Tightening critical bolts where exact torque values must be visually monitored and achieved, rather than estimated by a mechanical "click".

• Wind Energy: Tightening and auditing massive structural bolts on wind turbine towers, blades, and gearboxes.
• Heavy Machinery & Construction: Maintenance and manufacturing of mining trucks, excavators, cranes, and agricultural equipment.
• Structural Engineering: Quality control for high-tension anchoring bolts used in steel bridges, building frames, and civil infrastructure.
• Marine & Railway Systems: Tightening critical fasteners on large ship engines, propulsion systems, and railway track components.

• • Torque Range: 200 – 2100 N·m
  • Minimum Graduation (Increments): 20 N·m
  • Accuracy: ±3% of the indicated value (compliant with ISO 6789)
  • Direction: Bi-directional (measures both clockwise and counter-clockwise)
  • Square Drive Size: 1 inch (25.4 mm)
  • Total Length: 2140 mm (2.14 meters / approx. 7 feet) with the extension handle attached
  • Total Weight: Approx. 12.8 kg (28.2 lbs)

• • Memory Pointer (-S): Includes a red follower needle that captures and stops at the maximum peak torque achieved for easy quality control data logging.
  • Length-Independent: Built with a unique internal mechanical leverage design so accuracy is not affected by where the operator holds the handle.
  • Modular Construction: Comes shipped as a two-piece set consisting of the main wrench body and a heavy-duty extension handle required to safely pull up to 2100 N·m.
