Torque Wrench Calibration Tester

The Torque Wrench Calibration Tester is a specialized instrument used for the calibration and verification of torque wrenches, torque screwdrivers, and other torque-controlled tools. It is mainly used to test various preset torque wrenches, digital torque wrenches, preset-type torque wrenches, torque screwdrivers, screwdrivers, and other instruments or products involving controlled tightening force.

Applications

The instrument is widely used in:

Electrical Manufacturing — calibration and verification of torque-controlled tools used for electrical assembly.

Machinery Manufacturing — checking the accuracy and performance of torque wrenches and torque screwdrivers.

Professional Testing and Inspection — torque measurement, calibration, and quality verification.

Scientific Research — torque measurement and performance evaluation of torque-related instruments.

Applicable Standard

JJG 797-2013 — Verification Regulation of Torque Wrench Calibrators

Available Types

Manual Type — Suitable for routine torque wrench calibration and verification.

Fully Automatic Type — Provides automated test control and measurement, suitable for higher-efficiency and more standardized calibration operations.

Technical Specifications

Key Features

High-Precision Measurement: Equipped with a high-precision torque sensor. The accuracy class can typically reach ±0.3% to ±0.5% FS, with some models available in Class 0.3. ensuring accurate and reliable torque measurement.

Intelligent Interface and Display: Generally equipped with a large 7-inch or 8-inch color touchscreen for intuitive operation. Real-time torque values, peak torque, and torque curves can be displayed.

Multiple Measurement Modes: Supports various modes, including real-time value, peak value, and automatic peak value, to meet different calibration and verification requirements.

Multiple Torque Units: Supports automatic conversion between N·m, kgf·cm, lbf·in, and other torque units for convenient use under different measurement standards.

Bidirectional Measurement: Supports torque measurement in both clockwise and counterclockwise directions, with rotation direction indication.

Data Storage and Export: Built-in data storage allows large amounts of test data to be saved. Data can be exported to a computer or USB drive via USB, RS232. and other interfaces for report generation and further analysis.

Intelligent Alarm and Protection: Upper and lower torque limits can be preset. The instrument provides audible and visual alarms when the measured value exceeds the preset limits and includes overload protection. Some models also feature automatic power-off to reduce energy consumption.

Multiple Equipment Configurations: Available in various configurations to meet different application requirements, including benchtop, portable, pneumatic/electric dedicated types, and dual-sensor redundant designs.
