High-precision telemetry integration for racing, tuning, and specialized automotive systems.
Established in 1986, Ruian DongOu Automobile Meter Factory stands as a premier professional enterprise dedicated to the research, development, and high-precision production of automotive instrumentation systems. With nearly four decades of manufacturing heritage, we have engineered a highly mature and comprehensive technical ecosystem, bolstered by stable, state-of-the-art production capabilities that serve OEMs, racing teams, and aftermarket customizers worldwide.
Our strategic operations focus on two targeted brand portfolios:
Jointly developed with an Australian partner, focusing exclusively on elite-tier rally and track racing dashboards. Our products offer hyper-precise sensor arrays, low latency OBDII decoding, and IP-rated dust/water protection.
Specialized tuning instruments spanning boost, oil pressure, water temperature, exhaust gas temperature, and tachometers, customizable across standard form factors (52mm, 60mm, and 85mm).
Meeting requirements for reliability, compliance, and large-scale industrial distribution.
Modern commercial fleets, performance vehicle conversion yards, and industrial equipment builders operate in a landscape where mechanical gauges are giving way to digital instrument clusters. High-reliability dashboards must process multiplexed CAN-bus signals, display critical telematics in real-time, and withstand extreme operating environments without failing.
We supply high-degree OEM/ODM flexibility to modify display layouts, boot screen graphics, physical bezels, mounting brackets, and sensor parameters. Enterprise clients can align instrumentation units directly with their proprietary branding.
Whether using standard OBDII protocols, J1939 CAN-bus protocols for commercial equipment, or external sensor networks, our dashboards serve as central data gateways with high electromagnetic immunity.
Our manufacturing processes follow international standards, securing reliable operational limits, minimal latency, and robust structural housings. This ensures clean approvals in EU, NA, and APAC markets.
The development of automotive displays at Ruian DongOu focuses on increasing refresh rates, reducing display power draws, and improving ambient visibility under direct sunlight. Our upcoming generation of dashboards integrates advanced digital processing architectures:
From standard road cars to competitive drag racing, we engineer specialized tracking platforms.
Track racing demands fast processing speeds. Our SincoTech DO928 series decodes 9 core parameters simultaneously, featuring adjustable high-intensity sequential shift indicators. Track-tested sensor terminals capture oil temp, exhaust gas temperatures, and pressure values with high accuracy.
For car enthusiasts, customization is key. Our GragonGauge brand offers multiple digital and analog combinations (boost, volt, water temp, tachometer) in 52mm, 60mm, and 85mm sizes. These fit into standard A-pillar pods or dashboard panels, matching modern and vintage interiors.
For light duty trucks, specialty off-road vehicles, and construction machinery, our heavy-duty digital clusters provide clear status monitoring, high water/dust protection ratings, and vibration resistance.
Exporting sensitive electronic systems demands reliable supply chain logistics, protective packaging, and international certifications. Ruian DongOu manages quality control from procurement of electronic components to final burn-in testing.
With over 38 years in the global market, our logistics channels guarantee quick transit times, clear customs processing, and drop-ship capabilities. We provide technical support documents, installation diagrams, and wire-color legends in multiple languages to reduce installation troubleshooting.

Expert technical support answering B2B integration queries.
Our dashboards support dual integration modes. First, they interface with standard OBDII protocols (connecting to the vehicle's diagnostic link connector under ISO 15765-4 CAN protocols). Second, they connect directly to our specialized external sensors (included in our sensor kits) for older or custom race vehicles without OBDII setups. This allows monitoring of key metrics like oil pressure, exhaust temp, and boost levels.
Yes, for bulk orders, we support startup splash screen adjustments, physical casing branding, and custom packaging. Minimum Order Quantities (MOQs) depend on the level of software customization needed. Please reach out to our factory sales department for details.
Our Bluetooth-enabled dash kits (such as the DO922 and DO904) use a dedicated transmitter that wires directly to the sensors inside the engine bay. The transmitter communicates with the dash monitor via an encrypted, low-latency Bluetooth link, preventing signal dropouts and RF noise interference from the alternator and ignition coils.
Our manufacturing processes follow CE and ISO 9001 factory production guidelines. Our products undergo rigorous quality inspection, including high/low temperature limits, vibration tests, and dust/water protection ratings.
Yes. While racing dashboards are typically designed for 12V automotive setups, we offer dedicated dual-voltage compatibility (12V/24V) across several dashboard configurations and digital gauges (such as our 52mm dual gauge series) to support light duty transport and commercial equipment.
