TorqueLab® LTT-Series Torque Analyzer

The torque analyzer is designed for calibrating tools, joint testing, auditing and measuring torque. Torque tools go out of calibration with use. To maintain consistent accuracy, torque tools must be checked periodically for wear or defective parts. A power or hand torque tool is a measuring tool that must be properly calibrated and maintained. The LTT-Series is an advanced torque testing and documentation solution. Using a quality torque tester makes a safer world through accuracy and precision. Controlling torque is essential for companies to ensure their product’s quality, safety and reliability isn’t compromised.
