High-performance 80mm and 52mm gauges designed to withstand cold climates and high vibration marine environments.
Norway represents one of the most demanding operational environments in the world. From deep-sea maritime fleets operating in the North Sea to subzero land exploration machinery, mechanical indicators and electronic dashboard monitors are subject to extreme temperature swings, constant saline corrosion, and severe mechanical vibration.
The Norwegian industrial sector, focused heavily on shipbuilding, offshore aquaculture, and the oil and gas sector, requires instrumentation that complies with strict Nordic standards. Under these conditions, the 80mm instrument format has become the standard for primary tachometers and telemetry monitors. The larger display ensures that engineers, pilots, and heavy equipment operators can safely read critical values instantly under adverse weather conditions, night cycles, or high-sea turbulences.
Simultaneously, Norway’s rapid transition toward electric marine vessels, hybrid aquaculture feeders, and performance racing markets (such as the Gatebil performance communities) has shifted demand towards multi-functional, digital dashboards with high bus integration capabilities (OBDII, CAN-bus, Bluetooth link).
The development standards behind our 80mm and 52mm gauges designed for industrial compliance.
Utilizing high-torque micro stepper motors that guarantee smooth needle response, avoiding lag and flutter under heavy machinery operation.
Processing data from sensors in milliseconds, avoiding latency. Highly accurate readouts for vital pressure, temperature, and RPM ranges.
Anti-fog lenses coupled with waterproof rubber rings. Ideal for exposed marine steering wheels, open-cabin vessels, and coastal applications.
Ruian DongOu Automobile Meter Factory (established in 1986) integrates advanced automated machinery, clean room SMD placement lines, and robust quality control systems to minimize human error and scale output efficiently. This direct integration is key to providing Norwegian clients with consistent pricing, reliable lead times, and certified quality.
Our facility maintains strict traceability for raw materials, ensuring that steel housings, electrical components, and glass screens comply with standard automotive regulations. By consolidating custom design and tooling under one roof, we significantly reduce time-to-market compared to Western competitors.
For Norwegian distributors and OEM customizers, this infrastructure means we can easily scale production from low-volume prototypes (50-100 units) to high-volume batches (over 10,000 units), backed by testing protocols that match European standards.
Decades of manufacturing expertise and global market presence.
Exporting electrical parts to Norway requires strict adherence to European Union standards, as well as specific local expectations regarding product lifetimes. Norway's Product Control Act and EE-register regulations demand that all electronic equipment imports display clear CE marks, comply with RoHS restrictions on hazardous materials, and have proper recycling processes in place.
At DongOu, all our gauges, including the SincoTech and GragonGauge series, undergo electromagnetic compatibility testing (EMC) to ensure they do not interfere with high-sensitivity GPS, sonar, and communication equipment standard on Norwegian maritime vessels.
Furthermore, our custom wiring harnesses are wrapped in flame-retardant heat shrink tubing, matching maritime flame safety criteria. When you buy from DongOu, you receive complete documentation to simplify import clearance and customs inspections in Norwegian ports like Oslo, Bergen, and Trondheim.
A trusted manufacturing leader in automotive instrumentation systems since 1986.
Established in 1986, Ruian DongOu Automobile Meter Factory is a professional enterprise dedicated to the research, development, and production of automotive instrumentation systems. Since its inception, the company has cultivated deep expertise in the industry for many years, building a mature and complete technical system and possessing stable and efficient production capabilities. We have established a strong reputation in the field of automotive instrumentation globally.
The company boasts a comprehensive and diverse product portfolio, with two core brands, each with a clear positioning and advantages:
SincoTech: A high-end instrument panel brand jointly developed with an Australian partner. This brand focuses on the racing and motorsport sector. Thanks to its stringent R&D standards and strict production control, product performance and quality reach the high end of the industry, meeting the high-precision data requirements of racing scenarios.
GragonGauge: A brand specializing in various modified instruments, covering core types such as tachometers, boost gauges, vacuum gauges, water temperature gauges, oil temperature gauges, oil pressure gauges, voltmeters, air-fuel ratio gauges, and exhaust temperature gauges, while also providing warning lights and mounting brackets. The brand covers popular specifications including 52mm (2 inches), 60mm (2.36 inches), and 85mm (3.75 inches), matching diverse installation and usage needs.
The complete range of 12V/24V compatible instrumentation systems for our Norwegian clients.
Technical support, delivery, and customization answers for B2B buyers in Norway.
Yes, our gauges are specifically designed and tested to operate reliably at temperatures down to -40°C. We use anti-condensation glass and heavy-duty internal lubricants to prevent needle lag in freezing temperatures.
We provide full OEM/ODM customization services. We can print your company or vehicle brand logo directly on the gauge face, change backlight colors, and adjust dial ranges (e.g., custom RPM ranges) according to your specifications.
Yes. Our dual display gauges and tachometers are designed to support wide voltage inputs (9V-36V DC), making them compatible with standard 12V automotive setups and 24V heavy machinery/marine electrical systems.
We offer FOB, CIF, and DDP shipping methods directly to Norway via ocean freight or air shipping (DHL/FedEx/UPS). Typical air delivery takes 5–8 business days, while ocean shipping to major ports like Oslo or Bergen takes around 35–45 days.
Our SincoTech dashboards connect via a dedicated Bluetooth central control unit or an OBDII harness. This collects sensor data directly from the ECU and transmits it to the digital LCD display, ensuring simple plug-and-play installation.
