Maretron Immersion Tank Temp Probe

The Maretron Immersion Tank Temp Probe is an essential sensor for any serious boater or angler who relies on real-time monitoring of fuel, water, or coolant temperatures. After years on the water, you learn that engine temperature management is critical to performance, efficiency, and longevity—this probe delivers the accuracy you need to catch problems before they become costly repairs. Whether you're tracking fuel tank temperature during a long offshore run or monitoring cooling system health in tight river conditions, this immersion probe integrates seamlessly into Maretron's marine monitoring ecosystem.

Built to withstand the marine environment, the Maretron Immersion Tank Temp Probe operates across a wide temperature range from –20°C to 80°C (–4°F to 176°F), covering everything from cold-start conditions to high-load engine scenarios. The probe's immersion design allows direct contact with tank or plenum fluids, providing fast, accurate readings that feed directly into your Maretron display system. Compact at just 0.3 lbs and measuring 7 x 1 x 7 inches, it installs discreetly without taking up valuable space in engine compartments or tank installations—a key consideration when working in the tight quarters of modern marine powerplants.

This probe is ideal for vessel owners who already trust Maretron's navigation and monitoring suite, or those planning to build out a comprehensive digital dashboard for their boat. Installation requires compatible Maretron display units and NMEA 0183 or NMEA 2000 backbone integration. Anglers and cruising boaters benefit most from continuous tank monitoring, as early temperature warnings can prevent fuel gelling in cold climates or heat-related engine stress during high-performance runs. For commercial or recreational vessels of any size, the Maretron Immersion Tank Temp Probe delivers reliable, marine-grade precision that keeps you informed and in control.
