💡 Frequently Asked Questions

Q: What is a digital torque gauge used for?

A digital torque gauge is a high-precision instrument used to measure, test, and calibrate torque on various fasteners, components, and torque tools. It provides real-time digital readings to ensure accurate torque application and quality control.

Q: How accurate are digital torque gauges compared to analog ones?

Digital torque gauges generally offer significantly higher accuracy and resolution than analog gauges. They reduce human reading errors by displaying precise numerical values directly on an LCD screen and often feature peak-hold functions.

Q: Can the digital torque gauge measure torque in both directions?

Yes, most professional digital torque gauges support bi-directional measurement, allowing you to accurately measure torque in both clockwise (CW) and counter-clockwise (CCW) directions.

Q: How often should a digital torque gauge be calibrated?

To maintain measurement accuracy, it is recommended to calibrate your digital torque gauge at least once a year, or after every 5,000 to 10,000 cycles, depending on usage intensity and industry standards.

Q: What should I do to properly maintain my digital torque gauge?

Store the gauge in its protective carrying case when not in use, avoid exceeding its maximum torque limit (overloading), keep it away from moisture and extreme temperatures, and remove the batteries if storing it for a long period.
