Head system:
Double sided ratchet head+ratchet torque square head: compatible with dual specifications, covering more types of bolts, easy to switch.
Central functional area:
Direction paddles: One click switch for forward/reverse, suitable for different fastening direction requirements.
Large LCD screen: high-definition display of torque values, units, and working modes, still clear in low light environments.
Communication port: Supports torque data export (such as connecting to a computer/mobile phone) for quality analysis and traceability.
Buzzer: Automatically sounds when the set torque is reached to avoid human error.
Operation buttons (C/U/V, etc.): Implement functions such as mode switching, unit conversion, data storage/clearing, etc.
Tail and handle:
Battery cover: easy to disassemble and replace, ensuring continuous operation.
Anti slip handle: Ergonomic design, comfortable grip, reduces fatigue from prolonged operation.
4、 Core functional highlights
Precise torque control:
The accuracy reaches ± 1% (within full range), ensuring that every tightening meets the standard and avoiding "over tightening fracture, under tightening loosening".
Multi mode adaptation:
Tracking mode: Real time display of applied torque, dynamic monitoring of tightening process.
Peak mode: Record the maximum torque during tightening for easy review afterwards.
Preset mode: Set the target torque, sound and light dual alarms (beep+screen display) when reaching the standard, and force standardized operation.
Flexible switching of units:
Supports units such as N · m, ft · lb, kgf · cm, covering metric and imperial standards, and adapting to the needs of different industries.
Data management:
Built in storage chip, capable of recording multiple sets of torque data; Combining communication functions to achieve data export and information management, adapting to the quality traceability system of modern production lines.
Durability guarantee:
The main body is made of chrome vanadium steel material, which is impact resistant, corrosion-resistant, and stable and reliable in dealing with complex working conditions such as oil pollution and vibration.
5、 Typical application scenarios
In the automotive field, torque calibration of tire bolts, engine components, and chassis screws meets original factory standards.
Mechanical assembly: Precision assembly of industrial equipment and machine tools to ensure the stability of equipment operation.
Aerospace: critical links such as cabin connection and pipeline fixation require strict torque control for safety.
Home appliance manufacturing: Assembly of core components such as motors and compressors to enhance product lifespan and reliability.
