Information Displayed On The Screen

The digital display screen will display the brand name of the wrench, current time, job number, bolt number, wrench operation mode, motor temperature, real-time output torque, and menu.

There are three buttons below the screen to enter the settings interface. In the settings interface, you can view wrench usage records, change language, change the direction of text on the screen, modify system settings, switch to torque calibration mode, and so on.

Specification Table:

*The commonly used torque in work should be less than 80% of the maximum torque of the wrench.

How to choose and maintain an electric torque wrench?

1. The tightening torque of the bolt is 80% of its yield limit, and the dismantling torque is 1.5-2.5 times the tightening torque. Based on the bolt specifications and strength grade, first determine the torque range that needs to be used.

2. The commonly used torque (rated torque) of a wrench should be less than 80% of its maximum torque value to ensure the optimal operating state of the wrench.

3. Choose the appropriate bolt sleeve according to the different bolt sizes.

4. Select or customize a suitable reaction force arm according to the operating conditions.

5. This product is not waterproof, please do not use it on rainy days or underwater.

6. The wrench should be properly stored after use, and should be recalibrated after maintenance or use for more than six months.

After Sales Service:

1. Free replacement of torque wrench component and new product if it's demaged or broken because of supplier's responsibility.

Application Cases:

Industry 4.0 Ready: Smart Bolting Solution with Data Traceability

Scenario: Critical Infrastructure & Quality Assurance

In high-stakes industries like Nuclear Power, Wind Turbine Installation, and Petrochemical Maintenance, every bolt’s tightening data is a matter of safety and compliance. The Bair BRAC-S series, equipped with optional Bluetooth and WiFi modules, transforms a traditional tool into a smart terminal.

How it works for your project:

Real-time Monitoring: Site supervisors can monitor torque output and angle precision in real-time via a mobile app or a local network, ensuring all bolting tasks meet the engineering specifications.

Digital Records (Data Logging): Say goodbye to manual error-prone logging. Each tightening cycle is automatically recorded, including Date, Time, Target Torque, and Actual Result.

Seamless Export: Easily export comprehensive bolting reports in CSV or PDF formats. These reports serve as vital "Quality Birth Certificates" for your projects, simplifying the acceptance process for European and Australian safety audits.

Continuous Power for Big Data: Being a plug-in (AC-powered) tool, the BRAC-S ensures that the smart module never loses connection due to battery depletion, providing 24/7 stable data transmission for large-scale assembly lines.
