Engineered for track and high-stress racing environments, our instrumentation integrates high-brightness OLED screens, multi-colored backlighting, and precision sensor setups.
In the modern performance automotive supply chain, digital race car gauges are no longer merely aesthetic custom retrofits; they are the baseline telemetry backbone of professional teams, privateer tuners, and special equipment builders. The sector has transitioned rapidly from slow-refresh mechanical needles to solid-state digital displays communicating over localized Controller Area Network (CAN-bus) protocols and OBD-II telemetry systems.
Ruian DongOu Automobile Meter Factory has remained at the absolute forefront of this technological shift. Established in 1986, we are a specialized global design, engineering, and manufacturing enterprise. Through our core brands, SincoTech (developed in joint collaboration with an Australian partner for the high-end racing market) and GragonGauge (our performance modification-focused line), we supply professional-grade digital dashboards to distributors, race team contractors, and customization shops across North America, Europe, and Australia.
A professional race dashboard must balance absolute data accuracy with high-refresh display technologies to ensure drivers receive real-time metrics without signal lag.
Digital racing systems require precise sensor arrays. While entry-level gauges operate on standard resistive signals, DongOu designs employ active transducers and direct analog-to-digital signal processing inside the sensor module itself. Our DO907, DO908, and DO904 SincoTech dashboard series feature unified sensor control boxes. This hub processes inputs for manifold boost pressure, oil temperature, oil pressure, exhaust gas temperature (EGT - utilizing type-K thermocouple probes), fuel level, and water temp before delivering a clean, digital data stream to the LCD or OLED panel.
Standard consumer displays wash out under direct sunlight and lag at freezing temperatures. DongOu solves this by utilizing industrial-grade high-brightness OLED displays (such as in the DO907) and active TFT screens with up to 7 color choices (as seen in the DO922 and DO926). With high contrast and wide viewing angles, these displays are readable even in open-cockpit race cars under changing direct sunlight.
For modern track cars, tearing down a dashboard to tap into individual sensors is inefficient. Our OBD-II series racing dashboards plug directly into the vehicle's diagnostic link connector (DLC) and communicate using standard protocols like ISO 15765-4 (CAN-bus), ISO 9141-2, and KWP2000. Additionally, our Bluetooth-enabled models (like the DO904 and DO921) transmit sensor hub data to the main display panel wirelessly, simplifying installation through engine firewalls.

As a direct manufacturer, Ruian DongOu Automobile Meter Factory provides extensive customization options for our global business partners. Whether you are an automotive distributor looking to build a brand identity or a specialty vehicle builder requiring custom scale calibrations, our production lines are fully optimized to handle your specifications.
Over the past three decades, we have continuously optimized our precision manufacturing facilities and custom calibration instrumentation. This enables us to maintain strict tolerances, ensuring that every stepper motor and sensor hub performs reliably under heavy vibrational and thermal loads.
From extreme off-road racing to high-altitude rally stages, our telemetry options are designed to perform reliably under challenging environments.
In competitive track racing, vital parameters like high-accuracy water temperature, oil pressure, and exhaust gas temperatures (EGT) must be constantly monitored. SincoTech OLED panels (like the DO907) compile these inputs and display them with minimal latency, allowing racing teams to prevent engine failures before they occur.
Off-road and rally vehicles subject instrumentation to heavy vibration and impacts. Our waterproof rally dashboards (such as the SincoTech DO908 sensor kits) are built with sealed housings and locking wiring harnesses to ensure reliable data transmission on any terrain.
For custom car builders, matching a gauge set to the vehicle's interior is crucial. The GragonGauge 52mm series provides analog mechanical looks backed by digital electronic accuracy, featuring adjustable 7-color backlights to match any factory cluster color.
Our facility features advanced component manufacturing, calibration, and product verification processes.
Technical information regarding installation, protocol compatibility, and bulk OEM capabilities.
Wholesale options and multi-system kits available directly from our factory floor.
