Material Composition: This LED voltmeter combines grade ABS polymer with metal components to create a robust housing that resists abrasion and physical impacts while maintaining longterm structural integrity. Enhanced Visibility Display: Featuring a bright blue LED digital screen that provides clear readability from multiple viewing angles, ensuring visibility in both daylight and lowlight driving environments. Simplified Mounting Process: Designed for straightforward installation without requiring vehicle modifications or tools, this gauge enables quick integration into various automotive, motorcycle, and ATV dashboard configurations. Dual Measurement Functionality: Capable of simultaneously monitoring and displaying both vehicle voltage levels (9V 36V DC) and coolant temperature readings with precise measurement accuracy for comprehensive vehicle system monitoring. Compact, Durable Design: A compact form factor with vibration resistance suitable for tight dashboard spaces, built to sustain reliable performance in automotive environments. Use scenarios: In daily driving cars or trucks, monitor battery/alternator health and coolant temperature to catch electrical faults or overheating early. On motorcycles or ATVs with limited dashboard space, install quickly for realtime voltage and coolant temperature readings. In DIY builds, restorations, or fleet vehicles where a universal 9V 36V DC input and coolant temperature display helps centralize monitoring.
