Veratron OL 43 Smart Marine Monitoring TFT Display

The Veratron OL 43 is a compact all-in-one marine monitoring display, tracking engines, batteries, tanks, and navigation data on a 4.3 inch optically bonded IPS TFT screen that stays perfectly readable even under direct sunlight thanks to its anti-glare mineral glass front.

Supporting both NMEA 2000 and SAE J1939 CAN protocols alongside 4 analog sensor inputs and HTML5-ready Ethernet connectivity, the OL 43 is built to integrate with modern digital networks and legacy analog sensors alike. An integrated NMEA 2000 converter, full engine diagnostics, and programmable alarm outputs give this display genuine functional depth well beyond a basic gauge, with a customizable multilingual GUI and graphical insights that make monitoring data intuitive rather than overwhelming.

Lightning-fast startup and a compact 85mm round form factor make the OL 43 easy to install into a standard panel cutout via spinlock, and its flame-retardant housing meets marine safety requirements for engine compartment-adjacent installation. IPX7 protection keeps the unit sealed against water intrusion, and it holds up reliably even in high-temperature environments. Browse more marine instruments and gauges at CritPro.
