3/8" Drive Digital Torque Tester, 25-250 in-lbs

Professional Torque Verification for Quality-Critical Applications

The Williams 2502-I-DTTW 3/8" Drive Digital Torque Tester is engineered for precise verification of torque wrenches and torque screwdrivers in manufacturing, assembly, automotive, aerospace, and industrial maintenance environments. With a working range of 25–250 in-lb and industry-leading ±0.5% accuracy, this tester helps ensure tools meet performance standards before they impact product quality or safety.

High-Accuracy Digital Measurement

This torque tester delivers ±0.5% accuracy (±1 count) from 10–100% of indicated test value in both clockwise and counterclockwise directions at 25°C. Its advanced internal load cell system provides consistent, repeatable measurements, supporting quality control programs and ISO-compliant calibration procedures. A Certificate of Calibration is included for traceability and documentation requirements.

Real-Time Touchscreen Operation

An intuitive touchscreen interface allows operators to monitor torque values in real time and capture peak results instantly. Users can easily toggle between Track, Peak, and First Peak operating modes, making it suitable for click-type torque wrench testing, digital wrench validation, and screwdriver verification.

Multiple Units of Measure for Global Flexibility

The tester supports ft-lb, in-lb, in-oz, Nm, and kg-cm, enabling seamless integration into domestic and international operations. Switching units is quick and simple, reducing setup time and improving workflow efficiency in mixed-tool environments.

Data Capture and Memory Storage

With a memory capacity of up to 500 records (complete check mode), the 2502-I-DTTW supports process control initiatives and tool performance documentation. Captured torque values can be reviewed immediately, helping technicians validate calibration status before returning tools to service.

Flexible Mounting and Portable Design

This tester can be wall-mounted or secured in a bench-top vise, providing versatility across calibration labs, tool cribs, and production floors. It is sold as a complete kit with a carrying case, AC/DC power adapter, and batteries, making it suitable for both stationary and mobile verification tasks.

Built for Industrial Environments

Designed to operate in temperatures from 50 to 90°F (10 to 32°C) and withstand up to 85% relative humidity, the tester is built to perform in demanding shop conditions. Dual power options (AC adapter or AA batteries) ensure uninterrupted operation during testing cycles.
