Established in 1986, Ruian DongOu Automobile Meter Factory has positioned itself at the forefront of the research, development, and high-standard manufacturing of automotive instrumentation systems. With over three decades of engineering excellence, the company has built a mature and complete technical framework. This foundation allows us to maintain stable, efficient, and high-capacity manufacturing operations that deliver class-leading telemetry to markets worldwide.
Operating with a dual-brand strategic portfolio, we address distinct segments of the performance automotive and industrial telemetry industries:
In terms of geometric dimensions, our components are supplied in standard, industry-accepted formats: 52mm (2 inches), 60mm (2.36 inches), and 85mm (3.75 inches) configurations. This ensures direct compatibility with existing dashboards, customized instrument clusters, and direct pod-mounting systems.
The global procurement market for racing instrumentation and custom dashboards has transitioned from purely cosmetic upgrades to complex data acquisition systems. Industrial buyers, original equipment manufacturers (OEMs), performance modification garages, and fleet integrators demand highly customizable, reliable, and latency-free digital dashboards.
Today’s procurement requirements focus on three core principles:
Modern racing engines operate near their thermal limits. The dashboard must process multiple analog sensor signals (oil temperature, oil pressure, EGT, water temperature) and display them in real time without lag, preventing catastrophic powertrain failures.
Whether for marine application, rally cars, off-road side-by-sides, or formula racers, components must withstand high vibrations (up to 10G) and severe dust/water ingress (IP65 up to IP67 waterproof standards on critical modules).
Enterprise clients demand dashboards that seamlessly communicate with modern ECUs through CAN bus, OBDII protocols, or high-accuracy analog sensor clusters, ensuring direct integration with minimum setup time.
Automotive system integration is not a one-size-fits-all discipline. Depending on the operational conditions, different architectures must be deployed. Below are the macro-industry solutions Ruian DongOu designs and manufactures for buyers worldwide:
Under the SincoTech brand, we engineer integrated digital race dash systems (such as the DO908, DO904, and DO921 series) that utilize dedicated, high-speed microcontrollers to compile and project raw data onto customizable LCD and OLED panels.
For custom builders, high-performance tuning shops, and restomod projects, GragonGauge offers standalone analog and digital-hybrid indicators. These gauges allow operators to target specific parameters such as intake manifold boost pressure, air-fuel ratios, exhaust temperatures, and battery voltages.
The future of performance driving telemetry rests on high-speed computing, wireless integration, and customizable software-defined user interfaces.
Our technological roadmap targets several key engineering milestones:
Integrating 4G/5G and Bluetooth modules with centralized cloud servers. This allows pit crews and race team engineers to monitor critical engine data in real time from anywhere in the world.
Transitioning to ultra-high-brightness OLED and IPS technology panels, with up to 1000 nits of brightness. This ensures visibility even under direct, harsh desert racing sunlight.
Offering scalable UI frameworks where B2B buyers can upload custom brand logos, configure specific alarm rules, and modify background visual elements in-house.
Ruian DongOu Automobile Meter Factory operates a strict quality management system to support global supply agreements. Every custom dashboard and sensor kit undergo visual calibration, thermal cycling testing (-20°C to +80°C), and vibration aging tests to prevent field failures.
We provide full OEM and ODM services for domestic and international customers. Clients can supply engineering drawings or performance parameters, and our engineering team will develop custom prototype casings, mounting plates, and system software to match their requirements.
