DTM104 Tachometer Core Performance Advantages

Standard 52mm Universal Mounting Size

This tachometer follows a standard 2 inch (52mm) universal design, fitting all standard 52mm dash gauge mounting holes on 4/6/8-cylinder gasoline vehicles. Covering a 0-8000RPM measuring range, it supports engine speed monitoring for sedans, pickups, and modified racing vehicles. No extra hole cutting is required for installation, as it aligns directly with existing dashboard openings.

Calibrated Electronic Sensing Chip

Each unit integrates an electronic sensing chip and completes three rounds of factory calibration, achieving a measurement error of ±2.5%. The signal refreshes 12 times per second, tracking engine RPM fluctuations with minimal pointer lag or jitter. This performance supports stable readings for both daily driving and track use scenarios.

Uniform White LED Backlight Dial

The unit features a white LED backlight with uniform light guide technology, producing glare-free illumination across the dial with no dark areas. The backlight component has a rated service life of over 50,000 hours. The black dial paired with a high-contrast red pointer enables clear data reading under direct sunlight and low-light night conditions, suitable for long-distance driving.

Complete Wiring Harness for Fast Installation

The full assembly weighs 0.0668kg, with a compact body that conserves console space. A complete color-coded wiring harness is included for straightforward plug-and-play operation. A single technician can finish the full installation within 8 minutes, cutting labor time costs for modification stores and service garages.

Multi-Environment Aging Test Verification

Every finished unit undergoes 72 hours of continuous vibration testing and temperature cycling tests from -25℃-75℃ before shipment. This testing verifies resistance to engine compartment temperature changes and bump vibration on rough roads, extending service life and reducing after-sales failure rates for aftermarket dealers and wholesalers.

Wide Compatibility for Gasoline Vehicles

This tachometer works with most gasoline-powered vehicles, with no strict model limitations within its supported cylinder count. Auto parts wholesalers can stock this single SKU to meet most customer replacement and modification demands, reducing inventory capital occupation and simplifying warehouse management for auto electrical accessories.
