Bright OLED Display for Instant Readability

The Blue Sea 1733 features a high-contrast OLED screen that remains clearly visible in bright daylight and low-light conditions. Unlike traditional LCD meters, the OLED display offers crisp readability without backlight washout—ideal for helm stations, dashboards, and electrical panels.

This level of clarity is especially valuable in systems that include a Blue Sea fuse block or distributed DC loads where quick voltage checks help prevent power issues before they escalate.

Compact Size with Flexible Mounting Options

Space is always limited in marine and mobile electrical systems. The 1733 Mini OLED Voltmeter is designed with a compact housing that mounts into a standard 1-1/8″ hole, allowing installation almost anywhere.

Its small size makes it easy to integrate alongside switches, breakers, or monitoring components without overcrowding the panel—whether you’re working with a centralized fuse panel or a remote monitoring location.

Reverse Polarity Protection for Added Safety

Electrical mistakes happen, especially during upgrades or retrofits. The Blue Sea 1733 includes reverse polarity protection, safeguarding the meter against accidental wiring errors.

This feature adds an extra layer of reliability in systems that rely on robust distribution hardware like a Blue Sea bus bar, where clean, protected connections are critical for long-term system health.

Waterproof Design for Marine and Mobile Use

Built for real-world conditions, the Mini OLED DC Voltmeter is designed to withstand moisture, vibration, and environmental exposure. Its waterproof construction makes it suitable for marine dashboards, open cockpits, RV interiors, and utility vehicles.

Whether installed on a boat, camper van, or off-grid power setup, it delivers dependable performance without compromising durability.

Ideal for Monitoring Battery and System Voltage

Consistent voltage monitoring is one of the simplest ways to protect batteries and connected electronics. The Blue Sea 1733 provides immediate feedback on system voltage, helping users identify:

• Low battery conditions
• Charging irregularities
• Voltage drops under load

This makes it a valuable companion to larger DC distribution systems built around Blue Sea Systems components.
