Established in 1986, Ruian DongOu Automobile Meter Factory has stood as a pioneer in the automotive instrumentation systems sector. Over the span of nearly four decades, we have continuously driven technological transformation to meet the needs of international clients.
Initially manufacturing analog mechanical gauges, our engineering group steadily grew and integrated computational electronics, developing digital control modules, CAN-bus integration, and high-brightness TFT liquid crystal displays. Our commitment to accuracy and hardware endurance under high thermal stress and physical vibration has positioned us as a highly trusted manufacturer in China.
We pride ourselves on offering comprehensive manufacturing pipelines, spanning initial PCB engineering, sensor matching, custom software integration, and structural housing design. With complete control over the production supply chain, we deliver high-reliability systems tailored to racing teams, individual enthusiasts, aftermarket modification companies, and global industrial OEM partners.
Catering to high-precision professional racing operations and automotive modification projects through two dedicated brands.
Co-developed alongside leading automotive instrumentation entities, the SincoTech brand specializes in professional racing dashboards. Engineered with high-frequency processing units and high-speed data transmission chips, these display units maintain an exceptionally low refresh latency (<10ms). They provide real-time updates for critical parameters on track, ensuring rally drivers and racers have instantly legible data when it matters most.
Optimized for aftermarket customization and enthusiasts, GragonGauge covers classic single-parameter modification gauges. Spanning dimensions from 52mm (2 inches), 60mm (2.36 inches), to 85mm (3.75 inches), this brand features tachometers, boost pressure readouts, vacuum sensors, water and oil temperature systems, oil pressure gauges, exhaust gas temperature (EGT) monitors, and voltmeters, designed with custom styling and adjustable warning parameters.
We provide full-scope customization services for racing teams, specialized vehicle builders, and brand retailers. From custom brand logos and customized color ranges to advanced CAN-bus programming and sensor parameter matching, our R&D department ensures our dashboards integrate smoothly with complex modern ECUs (LinkECU, Motec, Haltech) and custom engine applications.
Driving the future of motorsports telemetry by developing low-latency display processors, smart data hubs, and machine-learning diagnostic tools.
As vehicle systems shift toward hybrid powertrains, electric engines, and high-frequency CAN networks, we are upgrading our core processing units to accommodate high-speed data acquisition. Our upcoming dashboard systems utilize dual-core ARM Cortex processing units, facilitating fast boot times and smoother UI transition animations.
We are also transitioning from standard high-brightness LCD displays to transreflective, optically bonded TFT displays, which virtually eliminate reflections in direct sunlight. These screens operate with built-in ambient light sensors, automatically adjusting backlight configurations to maintain peak contrast without causing glare during night racing conditions.
Our future product roadmap focuses on cloud-connected telemetry dashboards. By integrating internal GPS modules, high-frequency 6-axis accelerometers, and 4G LTE communication interfaces, drivers can stream live lap times, engine diagnostics, and driver throttle/braking behaviors directly to pit crews or web analytics portals, minimizing setup hardware and processing times.
Introducing optically-bonded, high-luminance displays boasting 1000+ nits brightness for high contrast in harsh sunlight.
Adding automated protocol matching for mainstream aftermarket ECUs and standard OEM OBD2 systems, simplifying installation.
Integrating early-warning algorithms that track fluid temperature spikes and voltage drops to alert drivers of potential mechanical issues before they occur.
Engineered to handle extreme environmental demands across a wide variety of motorsports and automotive industries.
For circuit racing where fractions of a second count, our SincoTech digital panels deliver real-time RPM, wheel speed, water temperature, exhaust gas temperature (EGT), oil pressure, and lap times via ultra-bright shift light indicators. Configurable thresholds enable flashing alerts for oil drops or overheating, keeping engines running safely at their limit.
Dust, mud, and hard impacts degrade electronic instruments quickly. Our SincoTech rally series features IP65 waterproof seals, silicone-mounted internal circuit structures, and ruggedized housing to absorb high G-shocks. Paired with robust external sensor kits, they maintain accurate readings during off-road and rally stages.
Humid, high-salinity air quickly corrodes automotive components. We modify our instrumentation units for marine projects by treating circuit boards with anti-corrosion conformal coatings and sealing the glass panels to prevent internal condensation, delivering steady performance under harsh weather conditions.
Enabling customized cockpits tailored to specific driver needs and space constraints.
Every racing platform features unique cabin geometry. While sports coupes benefit from all-in-one digital dashboards, customized off-road trucks or drift machines often require physical arrays of supplementary instrumentation. Our design framework allows you to pair our central LCD dashboards with standalone 52mm or 60mm gauges in whatever arrangement you choose.
Because our devices utilize standardized signal calibrations, sensors for water temperature, oil temperature, and oil pressure can be split to feed both a central dashboard and physical secondary dials without signal drift or interference. We offer custom instrument pods, A-pillar mounts, and dashboard surrounds to simplify integration in any vehicle configuration.
Ensuring steady product quality, rapid lead times, and global shipping capabilities through our modern production facility.
Based in the manufacturing hub of Rui'an, China, the Ruian DongOu Automobile Meter Factory occupies a state-of-the-art facility optimized for high-volume automotive component production. Equipped with fully automated Surface Mount Technology (SMT) lines, solder paste inspection (SPI), and computerized Optical Inspection (AOI) units, we minimize manufacturing defects across all internal dashboard PCBs.
Our calibration lab houses digital temperature-controlled calibration ovens, pressure chambers, and signal generators, allowing us to inspect and adjust every sensor before dispatch. High-frequency vibration beds test all gauges against extreme road vibration, protecting against component failures on the racetrack.
We work closely with direct components suppliers, shielding our production schedules from local material shortages. Because we keep critical chips, LCD panels, and sensor housings in stock, we offer shorter turnaround times for bulk orders compared to smaller firms, keeping your retail pipelines running smoothly.
Automated component placement guarantees reliable soldering contact points on the board, preventing failures caused by engine vibrations or bumps.
Dashboards undergo testing cycle patterns ranging from -40°C to +85°C to ensure trouble-free operation in both winter conditions and hot cockpits.
We test each display unit on a high-frequency vibration bed to simulate rally stages and endurance racing, preventing internal display separation.
