Proto, J6470, Torque Tester, 5-50 in-lb, 1/4 in Drive, NIST Traceable, Track/Peak Hold/First Peak

This torque tester from Proto is engineered for professionals who demand precision in their torque measurements, making it indispensable for calibrating torques wrenches in various settings. With an accuracy of +/- 1% of the indicated value, it ensures reliable performance whether testing in a clockwise or counterclockwise direction. The device is NIST traceable, and each unit is accompanied by certification to meet strict compliance standards, giving users confidence in its accuracy. Versatility is a hallmark of this tool, as it operates in three modes—Track, Peak Hold, and First Peak—making it particularly suited for use with Click-style torque wrenches. Weighing just under six pounds and powered by a standard 9V battery, this tester provides up to 50 hours of continuous operation while maintaining a high sampling rate for accurate results. Additionally, it features a male square drive and includes a female-to-female square drive adapter, ensuring compatibility with a wide variety of tools. Whether you're in a workshop or on-site, this torque tester is a reliable companion for ensuring your torque measurements meet the highest standards.
