Explore our elite range of customized digital dashboards, intelligent rally screens, and multi-functional sensor gauges optimized for modern street modifications and professional racing environments.
Established in 1986, Ruian DongOu Automobile Meter Factory is a professional enterprise dedicated to the research, development, and high-precision production of automotive instrumentation systems. Since our inception, we have cultivated deep expertise in the industry for nearly four decades. By building a mature, complete technical system and maintaining highly stable, efficient production capabilities, we have established an unquestionable reputation in the global automotive instrumentation marketplace.
Our dual-brand structure addresses distinct areas of the market, satisfying both professional drivers and high-end automotive tuners globally. This enables us to cover everything from classic analogue dial setups to multi-parameter digital dashes.



We boast a comprehensive and diverse product portfolio under two core brands, each offering clear positioning and high-performance advantages:
Modern racing requires high-frequency data logging and real-time visualization. Standard analog instruments are no longer sufficient to monitor extreme modifications, high-pressure turbo setups, and high-RPM racing engines. This transition has driven the widespread adoption of LCD race car dash panels.
Modern racing dashboards depend on CAN (Controller Area Network) bus protocols and OBDII interfaces to retrieve data directly from the engine control unit. Our SincoTech range features high-speed data transmission speeds, preventing display lag even when revving up to 11,000 RPM.
Unlike standard consumer tablets, racing dashboards must remain perfectly visible under direct midday sunlight and extreme vibrations. Our custom displays utilize high-nit anti-glare coatings, adjustable backlights, and high-contrast layouts for instant readability at high speeds.
Engine bays are harsh environments exposed to water, mud, heat, and oil. Our dashboards, including the SincoTech DO908, are supplied with IP67-rated waterproof sensor kits, shielding internal electronics from extreme temperature variations and dust.
| Performance Metric | Traditional Analog Gauges | Modified Modular Gauges (GragonGauge) | All-in-One LCD Dash Panels (SincoTech) |
|---|---|---|---|
| Data Interface | Individual Analog Wiring (Sensor to Gauge) | Analog and Stepper Motor Signals | OBDII, Bluetooth, CAN-Bus & Custom Sensor Harness |
| Parameter Capacity | 1 Parameter per Dial | Dual-parameter layouts (Water Temp & Volts) | 9 to 18 Parameters simultaneously monitored |
| Alert Systems | None or Static Warning Light | Built-in warning thresholds with LED Indicators | Programmable RGB LED Shift Lights & Audible Alarms |
| Vibration & Shock Resistance | Medium (Sensitive to mechanical wear) | High (High-speed stepper motor architecture) | Military-grade solid-state PCB mounting |
| Installation Overhead | High complexity (Multiple gauge holes & wires) | Medium complexity (Pods & standard mounting) | Plug-and-play OBDII or single-bundle harness integration |
Sourcing directly from a mature Chinese manufacturer provides significant supply chain advantages. Our Ruian DongOu Automobile Meter Factory combines decades of localized engineering expertise with a robust component supply chain to deliver high-quality, cost-efficient instrumentation systems.
We handle all aspects of manufacturing in-house, including PCB surface mounting (SMT), plastic injection molding, and assembly. This reduces outsourcing costs and guarantees strict quality control at every stage of production.
Whether you require a custom boot logo, localized language support, modified RPM limits, or custom CAN-bus integration, our R&D team can develop and deploy custom firmware modifications within short turnaround times.
Before leaving the factory, every unit undergoes thermal chambers, high-amplitude vibration benches, and voltage surge testing to verify performance on high-vibration race tracks, off-road trails, and marine vessels.
After more than 30 years of development, we have built a technical R&D team and production workforce with deep professional skills and a strong commitment to quality. Equipped with precision manufacturing equipment and professional inspection instruments, we achieve high-standard control from production to final packaging.
Furthermore, our comprehensive enterprise management system spans production scheduling, strict quality control (QC), supply chain logistics, and dedicated after-sales support. This reliable infrastructure ensures stable product output and continuous product improvement for our global partners.
Our dashboard systems are engineered for diverse motorsport and tuning applications around the world.
For custom cockpits, our modular 52mm and 60mm gauges can be combined within specialized dash pods. This allows drivers to monitor critical engine data with dedicated dials.
Our SincoTech digital dashboards display multiple parameters in a single, high-contrast unit, replacing multiple analog dials. This saves weight and simplifies installation in race vehicles.
Our instruments support a variety of mounting configurations. Gauges can be installed on A-pillars, dashboard consoles, or within customized center stacks depending on driver preference.

Our SincoTech dashboards retrieve data using two primary configurations: standard OBDII protocol (which connects directly to the vehicle's diagnostic port on post-2008 models) and our dedicated sensor-transmitter harness kit. For custom or high-end racing vehicles that do not use standard OBDII systems, our sensor kit tracks parameters like water temperature, oil temperature, oil pressure, exhaust gas temperature (EGT), boost, and RPM directly from the engine bay using waterproof hardware.
Yes. As a factory supplier (Ruian DongOu Automobile Meter Factory), we provide OEM/ODM customization services. We can pre-load your custom brand logo on startup, modify the scale ranges of parameter displays, change LED warning alert thresholds, and offer tailored packaging designs. Please contact our sales engineering department with your dynamic layout requirements and minimum order quantities (MOQs).
Our GragonGauge series utilizes micro-stepper motors instead of older air-core movements. This design provides high response speed, high precision, and stability under vibrations. This stepper motor system is ideal for track cars, off-road vehicles, and diesel builds where high vibration levels can compromise conventional mechanical dials.
Yes, all sensors included with our SincoTech models (such as the DO908 and DO926NB kits) are built with IP67-rated waterproof wire connectors. The housing components utilize weather-resistant threads, making them suitable for open-engine bays, marine consoles, and extreme mud environments. However, the main LCD screen itself is designed for in-cabin installation and should be protected from direct water spray.
Most of our digital racing instruments and gauges are engineered to work with standard 12V automotive electrical systems. However, we also manufacture dual-display models (such as our 52mm Dual Display Water Temp & Volt Gauge) that are compatible with both 12V and 24V applications, making them suitable for commercial vehicles, transport applications, and heavy equipment.
Every batch of gauges and dashboards undergoes strict quality control. This includes automated SMT inspection, sensor calibration checks, thermal cycle testing between -20°C and 80°C, and vibration testing. We ensure each dash panel accurately processes input signals before packaging to prevent issues upon arrival.
