As part of the trusted Blue Sea Systems lineup, the 1741 is built for dependable performance in demanding environments.

Bright OLED Display for Instant Readability

The Mini OLED Temperature Monitor uses a high-contrast OLED screen that remains easy to read in both bright daylight and low-light conditions. Unlike traditional LCD displays, the OLED technology provides crisp visibility without glare or washout.

This makes it ideal for dashboards, electrical panels, battery compartments, and other locations where quick visual confirmation matters.

Wide Temperature Monitoring Range

The Blue Sea 1741 monitors temperatures across a broad range, making it suitable for many marine and mobile applications.

Temperature range:

• -40°C to 125°C
• -40°F to 250°F

Users can easily switch between Fahrenheit or Celsius, allowing seamless integration into systems regardless of regional or personal preference.

Compact Design with Flexible Mounting

Space is often limited in marine and mobile electrical systems. The 1741 Mini OLED Temperature Monitor is designed with a compact housing that mounts into a standard 1-1/8″ hole, allowing installation in almost any convenient location.

Its small footprint makes it easy to pair with other panel-mounted components such as meters, switches, or a Blue Sea fuse block without overcrowding the panel.

Reverse Polarity Protection for Added Safety

To protect against installation errors, the Blue Sea 1741 includes reverse polarity protection. This added safeguard helps prevent damage to the monitor if wiring is accidentally reversed during installation or system upgrades.

This feature aligns with the safety-focused design standards found across Blue Sea Systems electrical components.

Waterproof Construction for Harsh Environments

Built for real-world use, the Mini OLED Temperature Monitor is designed to withstand moisture, vibration, and exposure commonly found in marine and mobile environments.

Whether installed near battery banks, engine rooms, or enclosed electrical compartments, it delivers reliable temperature readings without compromising durability.

Ideal for Monitoring Critical System Areas

Temperature monitoring plays a key role in preventing damage and extending the life of electrical and battery systems. The Blue Sea 1741 is well-suited for monitoring:

• Battery compartments
• Engine spaces
• Electrical panels
• Enclosed storage areas

When paired with proper distribution hardware such as a Blue Sea bus bar, it becomes part of a clean, well-managed DC system.
