Explore our high-performance line of digital dash displays, Bluetooth receivers, and precision gauge sensors designed for extreme motorsport environments.
Established in 1986, Ruian DongOu Automobile Meter Factory is a professional enterprise dedicated to the research, development, and production of automotive instrumentation systems. For over 38 years, our company has cultivated deep expertise in the high-precision instrument sector, building a mature and complete technical system while possessing stable and efficient production capabilities.
With our headquarters located in Ruian, Wenzhou—the capital of automotive parts in China—our factory is equipped with advanced manufacturing infrastructure, a state-of-the-art R&D facility, and dynamic testing chambers that simulate extreme track environments. This robust platform guarantees consistent output of high-reliability gauges and multi-function dashboards for global distributors, race teams, and aftermarket custom shops.
Innovating in automotive measurement and gauge engineering since 1986.
SincoTech (High-End Motorsport) and GragonGauge (Tuning & Modifications).
Exporting reliable dashboard systems across Europe, Americas, and APAC.
Tailored gauge faces, logos, parameters, and CAN-bus/OBDII protocols.
We operate two highly specialized brands designed to target distinct market segments, ensuring that whether you are equipping a professional racing fleet or providing aftermarket tuning tools, we have the exact solution:
Deep-dive analysis of B2B procurement requirements for global importers, trade networks, and professional tuning distributors.
We support extensive logo customization, personalized dial designs, customized backlighting color choices, and custom startup screens for bulk buyers looking to establish their private label presence in regional markets.
Different markets run on different telemetry configurations. We configure core engine sensors (oil temp, pressure, water temp, EGT) according to local metrics (Celsius vs. Fahrenheit, PSI vs. Bar, kPa, RPM ranges).
By optimizing our material supply chain, we offer competitive bulk pricing tiers. We accommodate medium-sized tuning companies while maintaining the massive capacity needed by global Tier-1 auto parts importers.
How we are engineering the future of high-speed vehicle telemetry, wireless data acquisition, and cross-platform dashboard displays.
Developing seamless plug-and-play integrations with native OBDII diagnostic protocols. Minimizing physical sensor wiring by pulling data directly from the ECU via high-speed CAN-bus networks, reducing installation time by 70%.
Deploying Bluetooth 5.0 and BLE sensor nodes to transmit engine bay analytics to the dashboard in real-time. Eliminating structural firewall drilling for wire runs, enhancing safety, and reducing electromagnetic noise interference.
Transitioning dashboard interfaces to high-contrast, wide-angle OLED screens. Developing Head-Up Displays (HUD) that adapt brightness dynamically to daylight, ensuring track drivers receive vital alerts instantly without eye fatigue.
Expanding the product catalog to include electric vehicle (EV) specific instrumentation. Integrating state-of-charge (SoC) parameters, motor temperature, regenerative braking monitors, and battery cell balancing data streams.
To ensure our products withstand the intense vibrations, heat, and G-forces of professional motorsport racing, Ruian DongOu Automobile Meter Factory implements a rigid 100% inspection process.
Our facility houses high-precision testing instruments, including automatic temperature calibration baths, vibration fatigue tables, and circuit aging chambers. Each instrument is calibrated against national sensor standards before packaging. Our management framework bridges raw material inspection, SMD production, final assembly, and after-sales tracking to prevent defect leaks.
This commitment to manufacturing quality has earned our factories domestic and international acclaim, securing long-term export relationships in North America, Australia, the UK, Japan, and Southeast Asia.
Our dashboards are deployed across diverse sectors demanding high-precision, low-latency engine telemetry.
Providing drivers with real-time shift lights, lap timing, and critical fluid temperatures to maximize track time and prevent catastrophic engine failures.
Ruggedized, waterproof sensor designs that monitor transfer case temperature, battery voltage systems, and turbo boost levels in rough terrains.
Compact 52mm gauges and 3.5-inch LCD displays that integrate seamlessly into restricted fairing spaces while offering weather-sealed reliability.
Corrosion-resistant bezels and anti-fog display lenses engineered to survive salt spray and continuous damp marine environments.
Key information regarding interface compatibility, custom manufacturing, and global factory logistics.
Our multi-function dashboards, particularly the SincoTech DO series, support standard OBDII protocols, connecting via Bluetooth receivers or directly to the CAN-bus system. They are compatible with the majority of 12V OBDII-compliant vehicles manufactured after 1996. For older or non-OBDII vehicles, we provide standalone sensor kits that connect directly to the dashboard's wireless transmitter module.
Yes, Ruian DongOu Automobile Meter Factory specializes in OEM/ODM customizations. We can screen-print your logo on the gauge dials, adjust startup screens on our digital LCD dashboards, modify LED backlight spectrums, and adjust physical parameters to match your catalog requirements. Minimum order quantities apply for full custom tooling.
SincoTech is our premium motorsport brand, engineered in partnership with an Australian design firm. It focuses on comprehensive multi-in-one digital dashboards, features advanced wireless data transmission, and utilizes high-performance LCD screens. GragonGauge is our dedicated aftermarket tuning brand, focusing on individual analog and digital-hybrid 52mm/60mm/85mm gauges, such as boost, oil temp, and EGT gauges.
Each sensor batch undergoes temperature-resistance testing from -40°C to +125°C, high-vibration sweeps matching real engine bay loads, and voltage surge protection verification. Our dashboard components are housed in UV-resistant ABS frames and covered with anti-glare glass to ensure visibility and durability in professional track racing conditions.
Complete your automotive tuning catalog with our reliable OLED display dashboards, narrowband sensor kits, and multi-functional gauge sets.
