85mm 6 in 1 LCD MultiFunction Gauge | Tachometer Fuel Level Water Temp Oil Pressure Voltmeter Hour Meter for 12V Boat Car

Replace multiple dashboard gauges with one compact 85mm LCD display. This 6 in 1 multifunction gauge tracks RPM, fuel level, water temperature, oil pressure, voltage, and engine hours in a single, easy-to-read screen. Designed for 12V and 24V systems, it works on boats, cars, trucks, and generators.

This all-in-one gauge simplifies your dashboard by combining six critical engine readings into one 85mm unit. The high-contrast LCD display is clear in bright sunlight and low light, so you can check your data at a glance. The 316L stainless steel bezel resists corrosion, making it suitable for marine environments.

Installation is straightforward with a standard 85mm cutout. The gauge supports programmable tachometer ratios and ohm signal inputs for fuel, water temperature, and oil pressure sensors. Reverse polarity protection and anti-fogging add reliability. Note that sensors are sold separately, allowing you to choose exactly what you need for your setup.

Whether you are upgrading an older dashboard or building a new one, this gauge reduces clutter and gives you a modern, accurate monitoring solution. It is built to handle tough conditions with an IP67 waterproof rating and a wide operating temperature range from -40 to 85°C.

Usage Scenario

Mark runs a small fishing boat and was tired of glancing at four separate analog gauges that were hard to read in direct sunlight. He replaced them with this 85mm 6 in 1 LCD gauge. Now he sees RPM, fuel level, water temperature, oil pressure, and voltage on one bright screen. The hour meter helps him track maintenance intervals. The stainless steel bezel has held up well to saltwater spray, and he appreciates that he only had to cut one hole in his dash.

Micro Comparison

Many single-function gauges require multiple dashboard cutouts and separate wiring, which adds complexity and clutter. This 6 in 1 display combines all essential readings into one unit, reducing installation time and giving you a cleaner dashboard. Its programmable inputs make it adaptable to different sensors, while the IP67 waterproof rating adds confidence for marine use.
