TorqueLab® LTT-Series Torque Analyzer

Mountz LTT-Series torque analyzers provide engineers and metrology professionals with an advanced solution for calibrating, verifying, and maintaining tool performance. It is compatible with Mountz’s reaction and rotary sensors, including the ones with angle measurement capacity.

Torque tools go out of calibration with use. They must be checked periodically for wear or defective parts to maintain consistent accuracy. Regularly auditing and validating tooling calibration is essential for reducing errors in your assembly process, ensuring compliance with international standards and preventing product defects for all manufacturers.

A torque analyzer is a vital instrument for a quality control program. Investing in a torque testing solution eliminates downtime and expenses for shipping tools back and forth to an outside service center. It allows you to calibrate instruments more often and reduce calibration turnaround times and costs.

The torque tester can be used with hand or power torque screwdrivers and wrenches. Use the built-in transducer within your torque range applications or purchase additional torque sensors with different torque ranges to calibrate and validate various tools.

The LTT is compatible with rotary torque sensors for joint testing and verifying a power tool’s performance. When testing power tools, operators must use a run down adapter to ensure reading accuracy and prevent damage to the torque analyzer.

Easily connect Mountz torque sensors to the Mountz LTT via cable using plug-and-play ARC II technology. Manufacturing teams can connect torque sensors and analyzers with a Mountz multiplexer.and easily switch between up to 4 sensors.

Regular tool calibration and torque testing processes ensure repeatable accuracy and adherence to international standards. With its easy-to-use interface, the Mountz LTT torque analyzer provides quick and easy torque tool validation and calibration.

Calibrate, Validate, and Maintain Your Tools
