Marine instrument that combines fuel level, oil pressure, water temperature and voltage readings into a single 85mm gauge. Ideal for boat owners who need clear, quick engine checks while underway. Is ELING Multifunction Gauge the right fit for your boat's panel and wiring?

⚡ At a Glance
  • Display & Backlight: 85mm round fitting with selectable 8-colour backlight for better readability in different light conditions
  • Best for: Small to mid-sized boats and sailboats needing consolidated engine readouts on one instrument
  • Not ideal for: Dash panels with less than 70mm clearance behind the panel

Combines fuel level, adjustable oil pressure, water temperature and a voltmeter into a single 85mm instrument. Signal ranges are configurable and the unit meets IP67 waterproof and dustproof standards.


Comprehensive engine monitoring - thanks to combined sensors for fuel, oil pressure, temperature and voltage

Fuel level reads 0-100%. Oil pressure scale selectable between 0-5 bar, 0-10 bar (default) or 0-25 bar. Water temperature range covers 40-120 °C and voltmeter measures 9-32 V DC, with configurable sender resistances for compatibility.

Four key readouts appear in a single 85mm aperture, simplifying panel layout and wiring. Adjustable signal compatibility reduces the need for custom senders.

Clear visibility day and night - with eight-colour backlight control

Backlight cycles through eight colours: red (default), green, blue, white, yellow, yellow-green, orange and purple, allowing selection to suit dashboard lighting.

Choose the colour that delivers the best contrast for your helm and reduce glare during night passages. Colour selection helps match other instruments for a coherent panel.

Marine-ready durability - with IP67 waterproof rating and wide voltage tolerance

IP67 waterproof and dustproof grade resists spray and brief immersion. Operating voltage range supports 9-32 V DC systems, covering common 12 V and 24 V boat electrics, and requires 70 mm clearance behind the panel for installation.

Robust sealing and broad voltage compatibility mean reliable service in exposed marine environments. Installation fits most standard 85 mm cut-outs with a modest mounting depth.
