PRODUCT DESCRIPTION
Comprehensive Multi-Information Display
Equipped with a high-definition LCD screen and LED backlit analog gauges, the instrument provides real-time monitoring of key vehicle parameters, including engine speed (0-3000 RPM), vehicle speed (0-120 km/h), fuel level (0-100%), engine coolant temperature (40-120℃), oil pressure (0-10 bar), and battery voltage (12-24V). Additionally, it features warning indicators for abnormal conditions such as low oil pressure, high coolant temperature, and brake system faults, delivering clear and timely alerts to the driver
High Precision & Stable Data Transmission
Adopting advanced CAN bus communication technology, the instrument achieves fast and accurate data acquisition from the vehicle’s ECU (Engine Control Unit) and other sensors, with a data update frequency of 10 times per second to ensure real-time synchronization of parameters. The analog gauges use high-precision stepper motors, with an error margin of less than ±1% for speed and RPM measurements, providing reliable data support for safe driving and vehicle maintenance
Durable & Environmentally Resistant Construction
The instrument housing is made of flame-retardant ABS plastic with a scratch-resistant surface coating, capable of withstanding impact forces up to 50N without structural damage. It meets IP6K5 protection standards, effectively resisting dust intrusion, water splashes, and high humidity (relative humidity 10%-95%, non-condensing). The internal electronic components are designed to operate stably in a wide temperature range of -40℃ to 85℃, adapting to harsh working environments such as cold plateaus and high-temperature deserts
User-Friendly Operation & Easy Maintenance
The instrument panel is designed with ergonomic button layouts, including independent buttons for switching display modes (trip A/B, average fuel consumption, total mileage) and adjusting backlight brightness (5 levels), allowing the driver to operate without distracting from driving. The detachable front cover simplifies maintenance—if the LCD screen or LED bulbs need replacement, the cover can be removed with standard tools in 2-3 minutes, reducing maintenance time and costs for fleet operators
