Sierra EA01080 Digital Voltmeter 2.5-30VDC LED Display

The Sierra EA01080 is a compact digital voltmeter designed for marine and automotive electrical system monitoring. This self-powered unit features a bright 3-digit LED display that provides accurate voltage readings from 2.5 to 30 volts DC, making it ideal for monitoring battery banks, charging systems, and onboard electronics.

Key Features:

• Wide voltage range: 2.5-30VDC measurement capability
• Bright digital LED 3-digit display for easy reading in all conditions
• Self-powered operation draws power directly from the circuit being measured
• Low current consumption of less than 30mA
• High resolution: 0.01V with floating decimal point below 10V for enhanced precision
• Fast 20ms sampling rate for real-time voltage monitoring
• IP67 rated waterproof and dustproof sealed construction
• Built-in reverse polarity protection prevents damage from incorrect wiring

The IP67 rating ensures this voltmeter can withstand harsh marine environments, while the self-powered design eliminates the need for separate power connections. The floating decimal point feature automatically adjusts for optimal resolution, making low-voltage readings easier to monitor with precision.
