DOACT Marine Engine Temp Gauge 52mm/2in 40-120 C for Boat RV

< p>Keep your marine and mobile machinery running safely with the DOACT Marine Engine Temp Gauge. This precise 52mm/2in water temperature gauge is designed to monitor engine coolant temperature from 40°C to 120°C, giving you immediate visibility into potential overheating and helping protect engines, generators, ships, and other equipment. Built for harsh environments, it combines robust materials with smart electrical design to deliver reliable readings when you need them most. The rugged IP67 waterproof construction and a 316L stainless steel front cover resist corrosion, salt spray, and humidity—so you can rely on accurate readings mile after mile, even in demanding marine and off-road conditions. The gauge operates across a wide voltage range (9–32V DC, with a brief allowance up to 36V for under a minute) while drawing minimal power, making it suitable for diverse setups without draining your system. Its durable surface finish and diversified stainless steel design ensure long service life in demanding environments. The unit is suitable for engines, generator sets, ships, construction machinery, agricultural machinery, modified vehicles, and more. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
