TFT Gauges: Advanced Instrumentation for Modern Vehicles
Progauges products introduce an advanced digital instrument cluster and TFT smart gauge series featuring 19 configurations, ranging from 1.44-inch single-function displays to 7-inch heavy-duty dashboards. Engineered for OEM/ODM integration, this series serves commercial trucks, buses, agricultural machinery, and electric vehicles. Supporting both analog signals and the SAE J1939 CAN bus gauge protocol, it communicates directly with the engine ECU to monitor oil pressure, coolant temperature, voltage, fuel levels, and battery SOC with exceptional precision and reliability.

Product Description
Overview
TG-0203 / TG-0210 is a 2.1-inch circular TFT digital voltmeter with a 480 × 480 high-resolution display, configured for either 12V or 24V systems. The 12V version covers 8.0–16.0 V with a red alert at or below 12.0 V; the 24V version covers 20.0–32.0 V with a red alert at or below 24.0 V. During an alert, the numeric display, bar graph, and warning light all turn red. The CAN Bus models (TG-0203-001 / TG-0210-001) use the SAE J1939 protocol, while the analog models (TG-0203 / TG-0210) measure voltage directly from the electrical system. Typical applications include heavy-duty trucks, buses, passenger cars, agricultural machinery, construction equipment, forklifts, and generator sets — for electrical system and battery condition monitoring. Available for OEM / ODM design development and aftermarket use, and supports integration on ICE (gasoline & diesel), Hybrid, and EV Vehicle platforms.
