SDTW Series Standard Digital Torque Wrenches

The SDTW series standard digital torque wrenches utilize strain gauge measurement principles and integrated circuit digital processing technology. They feature peak hold and alarm functions, with an accuracy class of 0.1 level. These wrenches comply with the requirements of the "JJG1103-2014 Standard Torque Wrenches" regulations.

Main Performance and Specifications:

Standard Range: 1Nm, 5Nm, 10Nm, 50Nm, 100Nm, 200Nm, 300Nm, 500Nm, 1000Nm, 2000Nm, 3000Nm, 5000Nm.

High-Precision Torque Sensors: The wrench heads are equipped with high-precision torque sensors with an accuracy of 0.05%, achieving a comprehensive accuracy level of 0.1%.

Resolution: 0.0001-0.1Nm, with an overload capacity up to 120% of the full scale (FS).

Strong Resistance to Lateral Forces: The wrenches use a pure torsional measurement method, unaffected by the loading point, ensuring high measurement accuracy, stable performance, and long service life.

Data Storage and Display: The wrenches have a function to store detected torque values online, capable of storing up to 999 sets in peak mode. They feature a high-definition OLED display and a 4200mAh rechargeable lithium battery, which can operate continuously for 20-30 days.

Portability and Certification: Each wrench comes with an aluminum alloy carrying case for easy transportation and is provided with a third-party calibration certificate.
