Digital Torque Wrench SN-135CN

1、 Product positioning: Expert in precise torque control for compact spaces
SN-135CN focuses on compact spaces and long-term work scenarios such as automotive interior assembly, electronic equipment maintenance, and small mechanical installation. With a lightweight design of 1.95kg and a compact total length of 42.5cm (16.7 inches) as the core, it balances "operational flexibility" and "torque accuracy", solving the pain points of limited turning in small spaces and insufficient precision of traditional wrenches.

Weight 1.95kg (not tiring to grip for a long time, suitable for continuous operation)
Dimensions 42.5 × 5 × 5cm (slender body shape, penetrating narrow spaces)
3、 Structure and Function Analysis
Head design:
High precision ratchet head: Adopting a double-sided ratchet structure (compatible with fast forward/reverse switching), compatible with multiple specifications of bolts (universal for hexagonal and square heads), the ratchet teeth are tightly engaged, and the rotation is smooth without jamming, improving the efficiency of small space operations.
Central Control Zone:
High definition LCD display screen: Real time display of torque values, units, and working modes, with high contrast between black and white text, and clear visibility in low light environments (such as under the car or inside equipment), bidding farewell to "blind twisting".
Multi functional button group:
Mode switching: Supports tracking mode (real-time torque display), peak mode (maximum torque recording), preset mode (standard alarm), covering the entire scenario of debugging, acceptance, and batch fastening.
Unit conversion: One click switch between N · m, ft · lb, kgf · cm, suitable for multiple industry standards such as automotive, electronics, and home furnishings.
Sound and light alarm system: When the set torque is reached, a buzzer will beep and the screen will flash synchronously, forcing standardized operation and avoiding over tightening (damaging parts) or under tightening (loosening structure).
Controller optimization:
Dual material anti slip grip: wrapped in black engineering plastic and orange rubber, with an ergonomic curve that conforms to the curvature of the palm, dispersing grip pressure; The surface anti slip texture enhances friction and maintains stable grip in humid/oily environments.
4、 Core functional highlights
Torque accuracy guarantee:
The accuracy reaches ± 1% (clockwise)/± 1.5% (counterclockwise) (within full range), and through rigorous calibration, ensures precise and controllable tightening torque every time, supporting the standardized requirements of high-end assembly.
Data management (scalability):
Built in storage module, capable of recording historical torque data (in combination with brand matching software/communication function, some models support Bluetooth export), to assist in quality traceability and process optimization (such as electronic equipment batch maintenance records).
Durable design:
The main body is made of chromium vanadium alloy steel, which is resistant to impact and wear, and can cope with complex working conditions such as workshop oil pollution and slight impact; The internal sensor has a high level of protection and low precision degradation after long-term use.
5、 Typical application scenarios
In the automotive field: seat rail screws, center console screen bracket, and headlight assembly fastening (to avoid damaging plastic parts and ensure assembly aesthetics).
Electronics industry: Precision screw assembly for server cabinets, industrial controllers, and drone racks (to prevent component damage under stress).
Home installation: Torque tuning for smart toilets, high-end cabinet hinges, and fitness equipment (balancing stability and quietness).
DIY repair: model assembly, vintage camera disassembly, small home appliance maintenance (precise torque control to protect valuable parts).
