Blue Sea -100A to 100A DC Meter Mini OLED Ammeter

DESCRIPTION

Compact Bidirectional DC Current Monitoring for Marine and Off-Grid Systems

Maintaining complete visibility over your power consumption and charging performance is critical in any mobile or off-grid electrical setup. This compact digital ammeter from Blue Sea Systems provides accurate, real-time monitoring of DC current from -100A to 100A. Engineered for demanding environments, it allows you to track both charge and discharge cycles effortlessly, helping to prevent unexpected battery depletion and equipment downtime in caravans, 4WDs, and marine vessels.

Daylight-Readable Waterproof OLED Display

Standard digital gauges often wash out in direct sunlight or fail when exposed to moisture and coastal air. This mini ammeter features a high-contrast OLED screen specifically designed to remain sharp and legible across varying lighting conditions, from bright midday sun on an open boat deck to pitch-black night navigation. The waterproof front face ensures reliable operation in exposed cockpit panels, 4WD canopies, and outdoor electrical enclosures where dust and water spray are constant challenges.

Flexible Installation and Circuit Protection

Space is often at a premium on dashboards and control panels. Instead of requiring complex rectangular cutouts, the threaded cylindrical body mounts cleanly into a standard 1-1/8" (Approx. 29mm) round hole, matching the footprint of common marine-grade socket outlets. To simplify integration into existing or custom wiring harnesses, the meter supports both positive-side and negative-side shunt wiring. Built-in reverse-polarity protection safeguards the internal electronics against accidental miswiring during installation, reducing the risk of costly component damage.

Key Features

  • Bidirectional Current Tracking: Monitors electrical flow from -100A to 100A DC to clearly show net charging or discharging status.
  • High-Visibility Screen: Bright, high-contrast OLED display is daylight-readable for clear viewing at any angle.
  • Marine-Grade Durability: Waterproof face design withstands harsh marine, RV, and off-road environments.
  • Versatile Wiring Options: Compatible with either positive-side or negative-side circuit configurations for easier installation.
  • Standardised Mounting: Compact threaded body fits neatly into a common 1-1/8" (Approx. 29mm) panel cutout.
  • Integrated Safety: Reverse-polarity protection prevents internal damage if leads are inadvertently crossed during setup.

Ideal Applications for Reliable Power Management

Whether you are diagnosing parasitic loads, verifying alternator output, or keeping an eye on high-draw appliances like inverters and winches, a dedicated panel ammeter provides instant feedback without relying on wireless apps. It is well suited for:

  • Marine dashboards, helm stations, and bilge control panels
  • Caravan, camper trailer, and motorhome battery management boards
  • 4WD dual battery systems and canopy power distribution setups
  • Off-grid solar enclosures and industrial DC control cabinets

Take the guesswork out of your battery system's performance with a reliable, marine-grade current monitor. Add the Blue Sea Systems Mini OLED Ammeter to your setup for clear, dependable DC current tracking on every journey.
