- Monitors DC current from -100A to +100A
- Supports positive or negative side wiring
- Bright, daylight-readable OLED screen
- Reverse polarity protection
- Compact footprint with 1-1/8″ round mounting
- Compatible with 12V and 24V systems
This ammeter is ideal for monitoring battery banks, inverter loads, DC distribution circuits, and charging systems where accurate current feedback is required.
Blue Sea 1733 Mini OLED DC Voltmeter – Yellow
The Blue Sea 1733 Mini OLED DC Voltmeter – Yellow offers instant voltage visibility in a sleek, easy-to-mount format. Voltage monitoring is one of the simplest ways to assess battery health and charging performance at a glance.
Highlights include:
- Bright, waterproof OLED voltage display
- Reverse polarity protection
- Compact design for flexible mounting
- Installs in a standard 1-1/8″ hole
- Optimized for 12V and 24V DC systems
This voltmeter pairs naturally with current monitoring tools to give a more complete picture of system performance during charging, discharging, and standby operation.
Blue Sea 1741 Mini OLED Temperature Monitor – Yellow
The Blue Sea 1741 Mini OLED Temperature Monitor – Yellow adds an additional layer of system protection by tracking temperature conditions inside battery compartments, electrical enclosures, or equipment bays.
Core features include:
- Temperature monitoring from -40°C to 125°C (-40°F to 250°F)
- Selectable Fahrenheit or Celsius
- Waterproof, daylight-readable OLED display
- Reverse polarity protection
- Compact 1-1/8″ mounting
- Compatible with 12V and 24V systems
Temperature awareness is especially valuable in lithium battery installations, inverter compartments, and tightly enclosed electrical spaces.
Why Mini OLED Displays Matter in Modern DC Systems
