52mm Tachometer with Hourmeter | 7 Color Backlight RPM Gauge for Car Boat

Monitor your engine performance with this 52mm tachometer gauge that combines RPM readings with an hourmeter. It offers seven color backlight options for clear visibility and an IP67 waterproof rating for reliable use in demanding environments. Whether you drive a car, truck, or boat, this gauge helps you keep track of engine speed and running time.

This tachometer connects easily to various signal sources like the tacho sensor, alternator, ignition coil, or crankshaft sensor. It works with both 12V and 24V electrical systems, making it a versatile choice for gasoline and diesel engines. The stainless steel and plastic construction resists corrosion and wear, so the gauge stays functional even in tough conditions.

The bright 7-color backlight lets you match the gauge to your dashboard style or switch colors for better visibility at night. The racing-inspired design adds a sporty look to your vehicle interior while giving you accurate, real-time engine data. With an included installation manual, setting up this gauge is straightforward for most DIY enthusiasts.

Choose from multiple RPM ranges (3000, 4000, 6000, 7000, or 8000 RPM) to match your specific engine type. The hourmeter tracks total engine run time, which helps you schedule maintenance and monitor usage. This gauge gives you the essential information you need to keep your engine running smoothly.

Key Features and Benefits

- 7 Color backlight that lets you personalize the gauge appearance and improve readability in low light

• IP67 waterproof rating that protects the gauge from water damage, even when submerged up to 1 meter

• RPM and hourmeter combined in one gauge that gives you two critical engine metrics without extra dashboard space

• Multiple RPM range options (3000 to 8000 RPM) that let you pick the right scale for your engine type

• Stainless steel and plastic construction that resists rust and wear for long-term reliability

Who Is This For

- Car owners who want a reliable tachometer to monitor engine RPM and track running hours

• Boat operators who need a waterproof gauge that can handle marine environments and occasional submersion

• Truck and diesel generator users who require a durable gauge compatible with 12V or 24V systems

• DIY mechanics and enthusiasts who prefer a straightforward installation with included instructions

Usage Scenario

Mark owns an older fishing boat and wanted to keep better track of his engine performance. After installing this 52mm tachometer, he could see exact RPM readings while cruising and use the hourmeter to know when it was time for an oil change. The waterproof housing gave him peace of mind during rough weather, and the blue backlight made the gauge easy to read on early morning trips.

Micro Comparison

Many basic tachometers only show RPM and lack an hourmeter, forcing you to install a separate device. This gauge combines both functions in one compact unit, saving dashboard space and reducing wiring. The IP67 waterproof rating also sets it apart from standard gauges that may fail in wet or humid conditions.

Questions and Answers

Question: Can I use this tachometer on a diesel engine?

Answer: Yes, this gauge works with both gasoline and diesel engines as long as it receives a pulse signal from the tacho sensor, alternator, or ignition coil.

Question: What does the IP67 rating mean for this gauge?

Answer: IP67 means the gauge is fully protected against dust and can be submerged in water up to 1 meter deep for 30 minutes without damage.

Question: How do I choose the right RPM range for my vehicle?

Answer: Select a range that covers your engine's maximum RPM. For most cars, 6000 or 7000 RPM works well. For lower-revving diesel engines, 3000 or 4000 RPM is suitable.

Question: Does this gauge work with a 24V electrical system?

Answer: Yes, the gauge operates on both 12V and 24V systems, with a voltage range of 9 to 32 VDC.

Question: Is the backlight adjustable or always on?
