12V 24V 52mm Car Voltmeter Gauge Set | Water Temp Oil Temp Oil Pressure

Keep an eye on your diesel engine's vital signs with this 52mm gauge set. It combines a voltmeter, water temperature gauge, oil temperature gauge, and oil pressure gauge in one compact unit, giving you the information you need to drive with confidence.

This gauge set is designed for diesel engines running on a DC24V electrical system. It provides real-time readings for voltage, water temperature, oil temperature, and oil pressure, helping you monitor engine health at a glance. The clear yellow backlight makes it easy to read in low-light conditions.

Each gauge has a 52mm diameter, making it a standard size for most dash panels. The set includes a water temperature gauge that reads from 40 to 120 degrees Celsius, an oil temperature gauge that reads from 50 to 150 degrees Celsius, a voltmeter that works with both 8-16V and 18-32V ranges, and an oil pressure gauge that reads from 0 to 10 Bar.

Installation is straightforward for those with basic electrical knowledge. The gauges are built with a plastic housing, keeping them lightweight and durable for long-term use in your vehicle or machinery.

Key Features and Benefits

- Four-in-one gauge set that monitors voltage, water temp, oil temp, and oil pressure, giving you a complete engine status overview

• Yellow backlight that improves visibility during nighttime driving or in dimly lit engine bays

• 52mm standard size that fits into most universal gauge pods and dash panels

• DC24V compatibility that is ideal for diesel engines in trucks, boats, and heavy equipment

• Lightweight plastic construction that reduces installation strain and resists corrosion

Who Is This For

- Diesel truck owners who want to monitor engine temperature and oil pressure on long hauls

• Boat operators needing a reliable gauge set for marine diesel engines

• Off-road vehicle enthusiasts upgrading their dash with essential engine monitoring tools

• Mechanics and DIYers installing a complete gauge set in a custom build or restoration project

Usage Scenario

Mark drives a diesel work truck through hilly terrain every day. He noticed the engine temperature seemed higher than usual but had no way to confirm it. After installing this 52mm gauge set, he could see the water temp climbing on steep inclines and the oil pressure dropping during idle. Now he adjusts his driving to prevent overheating and schedules maintenance before a small issue becomes a major repair.

Micro Comparison

Some gauge sets only include a voltmeter and water temp gauge, leaving you to buy oil pressure and oil temp gauges separately. This set combines all four functions in one package, saving you time and ensuring compatibility between the sensors and display. The yellow backlight also provides better contrast than basic white LEDs in direct sunlight.

Questions and Answers

Question: Does this gauge set work with a 12V system?

Answer: The voltmeter covers 8-16V, so it can read a 12V system. However, the gauge set is designed for DC24V diesel engines. For best results, confirm your vehicle's voltage before purchase.

Question: What sensors are included in the package?

Answer: The package includes one 52mm gauge unit. Sensors for water temperature, oil temperature, and oil pressure are sold separately unless stated otherwise in the listing.

Question: Is the backlight always on or switchable?

Answer: The yellow backlight activates when the gauge is powered. It stays on while the engine is running for continuous visibility.

Question: Can I install this gauge in a gasoline car?

Answer: This set is optimized for DC24V diesel engines. Gasoline vehicles typically use a 12V system, so compatibility may be limited. Check your electrical system before installation.

Question: How do I wire this gauge to my dashboard?

Answer: Wiring involves connecting the power, ground, and sensor wires according to your vehicle's wiring diagram. Basic electrical knowledge is recommended for proper installation.
