Explore our hot-selling custom dashboard kits and digital gauges, engineered for professional motorsports and enthusiast tuning.
Establishing benchmarks in professional automotive instrumentation systems since 1986.
Founded in 1986, Ruian DongOu Automobile Meter Factory is a leading manufacturer dedicated to the research, development, and production of precision automotive instrumentation systems. Over nearly four decades, we have cultivated deep technical expertise, established advanced production lines, and garnered international recognition for our stable and efficient manufacturing capabilities.
We pride ourselves on driving engineering breakthroughs. From traditional analog meters to state-of-the-art multi-function digital dashboards, our product catalog meets the rigorous demands of custom vehicle builders, professional racing teams, and industrial OEMs worldwide. Our commitment to strict quality control ensures every unit leaving our factory delivers outstanding field reliability and precision data readings.
38+ Years of Manufacturing Excellence: Deep-seated industry expertise and vertical supply chain integration.
Precision Testing Infrastructure: Equipped with advanced testing chambers and automated optical inspection systems.
Comprehensive Customization: Tailored services spanning OEM/ODM design, firmware modifications, and logo engraving.
Catering to high-end motorsport telemetry and highly customized vehicle modifications with distinct, specialized brands.
Jointly developed with leading Australian engineering partners, SincoTech represents our premium line of professional digital dashboards and rally clusters. Focus areas include:
Integrated Parameter Monitoring: Up to 18-in-1 multi-functional vehicle parameters displayed in real-time.
OBDII & Bluetooth Integration: Plug-and-play dashboard solutions utilizing reliable wireless links and direct CAN connections.
Ruggedized Build: IP65/IP67 waterproof housings built to withstand extreme desert rallies and vibration-intensive racing environments.
DragonGauge is our specialized brand for diverse modification gauges. Ideal for car enthusiasts and performance shops looking to customize instrumentation layouts. The range includes:
Core Indicators: Tachometers, boost gauges, water temperature, oil temperature, oil pressure, exhaust gas temp (EGT), and voltmeters.
Multiple Sizes & Backlighting: Available in 52mm (2"), 60mm (2.36"), and 85mm (3.75") diameters with 7-color switchable backlighting.
Comprehensive Kits: Supplying mounting brackets, digital sensors, warning light modules, and complete cabling harnesses.
How we integrate advanced electronics, CAN-bus decoding, and reliable materials into every custom instrument panel.
Our digital clusters utilize high-speed microcontrollers to query vehicle ECUs over J1939, OBDII, and custom CAN configurations. This ensures latency-free visualization of critical indicators like RPM, speed, engine load, and intake manifold pressure.
We are phasing in high-brightness OLED and anti-glare, transflective TFT displays. This ensures readability under direct midday sunlight or dark night driving conditions, with automatic dimming features connected to ambient light sensors.
For our analog gauge lines, we employ high-torque, ultra-smooth Japanese-engineered stepper motors. The internal micro-stepping driver ensures precision pointer movement, zero vibration, and instant response times.
We provide advanced solid-state sensors for pressure (oil/fuel) and temperature (water/exhaust/oil) that reduce signal noise and resist corrosion, outperforming traditional mechanical transmitters.
Our upcoming product roadmap includes dedicated telemetry panels for electric vehicles, displaying state of charge (SoC), cell temperature maps, regenerative braking efficiency, and motor status.
Incorporating Bluetooth 5.0 and Wi-Fi modules, future SincoTech dashboards will sync diagnostic logs directly to smartphone apps, facilitating drag-strip analysis and telemetry reviews for racers.
Providing specialized solutions configured for diverse vehicle platforms and operational environments.
In high-vibration racing conditions, mechanical gauges often lose calibration. SincoTech digital race panels display vital vehicle statistics in a single consolidated screen, protected by CNC-machined aluminum housings and waterproof connections. High-brightness shift lights alert drivers precisely when to shift gear, preventing engine damage.
For custom restomods and tuner cars, dashboards require individual placement. DragonGauge's 52mm and 60mm ranges allow custom positioning in dashboard pods, A-pillar mounts, or center consoles. Our 7-color switchable backlight lets drivers match their dashboard's retro aesthetic or coordinate colors with interior LED themes.
Long-haul trucks, buses, and marine applications require reliable, continuous monitoring of oil pressure, fuel levels, and voltage. Our dual-voltage (12V/24V) gauge compatibility and customizable alarms allow fleet operators to install warning systems before costly mechanical failures occur.
Agricultural equipment, excavators, and generators operate in dusty, outdoor environments. Our waterproof LCD series, such as the DO908, ensures mud, dust, and rain will not compromise internal circuitry. Custom OEM calibrations are also available to support non-standard sender curves.
Leveraging Wenzhou's automotive component ecosystem to deliver high value and quick lead times.
Ruian, located within the automotive parts hub of Wenzhou, China, offers a highly integrated supply chain network. By sourcing components, raw plastics, and semiconductor assemblies locally, we minimize production lead times and maintain cost advantages that we pass directly to our global OEM partners.
Our facility combines design engineering with automated assembly under one roof. With dedicated tooling workshops, high-speed SMT placement lines, and advanced CNC machining, we transition custom gauge ideas from raw schematics to production-ready samples in weeks, rather than months.
