CEM500N3X22D-G Digital Torque Wrench, 100～500 N.m

Tohnichi CEM500N3X22D-G is a high-precision digital indicating torque wrench engineered for quality inspections, precise torque verification, and controlled tightening in demanding assembly environments such as heavy automotive manufacturing, machinery installation, and general industrial maintenance. Delivering accurate measurements from 100 to 500 N·m via a 3/4" square drive with interchangeable QH22D ratchet head, this manual tool features dual LCD/LED displays for enhanced visibility, data memory for up to 999 measurements with USB/RS232C output, and judgment functions for immediate pass/fail feedback. Robust and ergonomic with an aluminum body, it supports bi-directional operation (clockwise and counterclockwise) for versatile use in tightening and loosening tasks, promoting operator efficiency and reducing the risk of over-torquing in high-force applications.
