Interchangeable Head Large-screen Digital Display Torque Wrench

The replaceable head digital display torque wrench are different from the general torque wrench, in which the ratchet wheel of the replaceable head wrench can be freely replaced with plug-ins such as opening mouth, plum blossom head and movable opening head. Both have powerful operation functions, including torque setting, unit setting, numerical storage, numerical clearance, as well as numerical output and user correction function. It is characterized by high precision, accurate measurement, stable performance, low power consumption and simple operation. The requirements for operators are reduced by installing digital display screens. It is applicable to bolt fastening and control in automobile industry, machinery industry, etc.

Product Detail

Product Features

● Backlit Display: Large screen for clear reading of measurement data.
● High Accuracy: Clockwise ±2% and counterclockwise ±2.5% accuracy within 20% to 100% of full scale.
● Bi-directional Operation: Capable of both clockwise and counterclockwise operation.
● Alarm Indication: Buzzer and LED alert when predetermined torque value is reached (peak limit and preset modes).
● Multiple Units: Four engineering units available (N.m, kgf.cm, ft.lbf, in.lbf).
● Versatile Measurement Modes: Real-time, peak, and preset modes for different measurement needs.
● Data Storage: Function to store and record numerical values for future reference.
● Automatic Shutdown: Powers off automatically after 5 minutes of inactivity to conserve battery.
● Overload Protection: Displays "oLoRd" and prevents further force when overloaded at 120% of full scale.
