High-Precision 50nm Digital Torque Wrench for Industrial Use

Our LD series features accuracy within +/-3% clockwise and +/-2% counter-clockwise. Each unit is supplied with a factory calibration certificate and fully meets ISO 6789 standards.

Our high-performance brushless motor eliminates carbon brush maintenance, generates no sparks (safer for petrochemical sites), provides 30% higher energy efficiency, and lasts up to 3 times longer than brushed alternatives.

Yes. The LD series features an intelligent digital control system. Once the pre-set torque is reached, the motor will automatically stop and trigger an audible/visual signal to ensure zero over-torque risk.

On a full charge with our 8.0Ah high-capacity battery, you can typically tighten approximately 150-200 bolts (depending on the torque setting and bolt size). We recommend keeping a spare battery for continuous heavy-duty work.

The LD series is rated IP54 for dust and water resistance. While it is built for harsh construction and mining environments, we recommend avoiding complete submersion or prolonged exposure to heavy rain.
